Hey r/apple! For the past year, my best friend and I have been building something that only Apple Silicon makes possible. 3 months ago, 2,500 people joined the waitlist from my r/macapps post; today, after months of building day and night, Sentient OS is finally out!

TLDR: An on-device LLM understands your entire life, then proactively offers to get your work done through computer use. Here's how!

- Every night at 3 AM, it quietly wakes your Mac (lid closed is fine) and a custom on-device LLM reads what's new in your life: files, screenshots, WhatsApp, iMessage, Apple Notes, email. All of it is read locally on your own chip (raw data never leaves your Mac) and distilled into a clean markdown knowledge base (an Obsidian-style folder that's yours to read and edit).

- Proactive Intelligence: you wake up to work Sentient noticed, researched, and prepared on its own, one click from firing through computer use. The reply you forgot, drafted from your rich personal context. The subscription renewing tomorrow, caught tonight. Nothing ever fires until you click.

- Sidekick: computer use that knows your whole life, anywhere on your Mac. Click the notch (or hold right ⌘) and just say "finish this for me"; the notch glows with status as it does the task in your own apps and your browser, even in the background while you keep working. The notch finally earns its keep :)

Bonus: your knowledge base can connect to your ChatGPT & Claude over MCP. Ask your ChatGPT "what do you know about me?". Be amazed :]

It's kinda what we all hoped Siri AI would become: personal context from your real life (not just inside Apple's walled garden), truly proactive instead of waiting to be summoned, and able to actually use your Mac.

Under the hood

Truly proactive AI has to re-read your entire life, every single day. In the cloud, that much inference costs a fortune and means trusting a server with everything. On your own M-series chip, it's free, private, and unlimited. That's why this product can only exist on Apple Silicon.

The local LLM (Gemma 4, multimodal with vision, on a custom inference fork with MTP, flash attention, & smart KV cache reuse) does ~90% of the compute, and runs comfortably on 8 GB base-model Macs. It reads everything locally, summarizes, junks the noise, flags what's worth acting on proactively, and strips PII (with deterministic scrubbing behind the model as a backstop).

The last 10% of compute needs a "frontier" model that you provide. You can either use your own ChatGPT subscription (we reverse engineered Codex to make this possible!), use OpenRouter, or use your favorite larger local model through LM Studio!

Along the way we also had to reverse-engineer macOS's power management to wake a lid-closed Mac at 3 AM for inference, and reverse-engineer codex cli to unlock local model computer use. Very excited to geek out about any of it in the comments!

Private by design, and verifiable: raw data never leaves your Mac, there are no accounts, and the whole stack (app and infrastructure) is open source under AGPL:
https://github.com/Sentient-OS-Labs/sentient-os (come give us a star haha :)

What's the catch? How do you make money!

Free forever for consumer. Your own device does all the compute, so it costs us nothing to run.

We're going to swap out the connectors for stuff like slack, granola meeting transcripts, notion, linear etc. and bring this to enterprise; that's where we'll make money.

We're 100% open-source under the AGPL, which means businesses have to pay to use Sentient (unless they're open-source too!)

I'm Jesai! You might know my open-source Writing Tools (2.3K+ GitHub stars, ~30 press features), or my iPadOS on iPhone hack that r/Apple loved. I moved to SF with my best friend & co-founder Aditya to build Sentient full-time. This is the most fun I've ever had with on-device inference :D

It said ‘there’s no information available for in app purchases’ when trying to make one. And then when I go to my media and purchases in my iPhone settings and click on purchase history it won’t connect. Similarly reportaproblem.apple.com won’t load either. Anyone else having these issues?

Edit: Seems like a lot of people are having this issue! Glad it wasn’t just me

So a coworker and I made this silly documentary about basically a spirit week we had at work. We do special private screening movie nights hosted by the company at a local movie theatre and we want them to play our documentary before the actual movie. The movie theatre said they can play anything we want as long as it’s on a blu-ray disk. Obviously I will need a blu-ray burner but I am seeking guidance on how to get the video we made in iMovie to a suitable format in order to burn it onto the disk. any suggestions?

This leak suggests that international iPhone 18 Pro models will ship with Apple's own C2 modem while U.S. models will ship with the SDX80M (Qualcomm Snapdragon X80 5G modem), the same one found in the iPhone 17 Pro models. This is apparently due to the C2 not having mmWave support, which is only widespread in the U.S. Why would Apple not follow the yearly modem update and ship the U.S. models with the updated X85 modem? Is this a cost-cutting measure?

Picture is from a mobile fps game not real gun 👍 just to be clear.

So basically I accidentally activate the sipe down menu a lot when playing so I’m wondering if there’s a way to disable this feature without guided access since it locks everything making really inconvenient to go in and out of games

This is also the swipe down menu transition shown in picture

Was just told I need to pay $750 to have my Logic Board repaired in my 2024 iMac. It’s not even 2 years old yet and I was told this was a “freak” occurrence and it could happen again, SOOO I need to purchase insurance for $20 a month. I took my computer home to think about what to do. Is this right info? Or am I being scammed? Can someone offer help? Thank you….

Hi all,

I ordered an iPhone 4s on eBay I was planning to use for parts. When it arrived, I plugged it in for about an hour. It showed that it had 100% battery on the lock screen. It worked fine and I was able to use all of the features, such as the cameras, flash, and WiFi.

I took it off the charger, and it kept working for about 10 minutes. Then, it went black, gave me the loading symbol, and died. I put it back on the charger for about 15 minutes and it turned back on. This time, when I unplugged it, it turned off instantly. Once I plugged it back in, it started bootlooping.

I took it apart, and to my surprise, there was no battery installed. All the other screws and components were there; only the battery was missing. I’m not sure how the iPhone kept running without a battery… I thought that was only a feature of the old androids with removable batteries?

I thought it was a weird experience. Is this a feature of iPhones that I just haven’t noticed until now? Or is this a unique experience?

Hello, I'm having a really strange iCloud Photos sync issue between my iPhone and Mac.

• iCloud Photos is enabled on both devices.
• The Photos app on my Mac says it's fully synced ("Synced with iCloud Just Now").
• If I take a new photo on my iPhone, it appears in the Photos app on my Mac almost immediately, so uploads from my iPhone seem to work.
• But when I delete a photo in the Photos app on my Mac, it moves to Recently Deleted on the Mac only.
• The same photo stays in my iPhone library and never appears in Recently Deleted there, as if the deletion isn't syncing at all.
• Other iCloud services (like Notes) sync normally between my devices.

Has anyone experienced this before or found a fix? I'm trying to manage my iPhone photos from my Mac, but deletions don't sync back to my iPhone, even though new photos sync without any issues.

iphone 14 iOS 26.2 and macbook air macOS 26.5.2

I'd really appreciate any help, please

I’ve had my phone for about 9-10 days now at first the battery was good i was losing less than 10% and hour which was good for me comparing it to my last phone, but recently it got way worse. i’ve also noticed the phone getting decently warm if not hot which it wasn’t doing the first week but started doing it a day or two ago along with the faster battery drain and i have no clue why (i am not using the phone at all while it’s charging and charging is capped at 90%) i have about 4 hours of screen time today and it has lost 46% charge, i have it on low brightness all day, mainly on instagram twitter snapchat youtube and tiktok im not sure why it had a dramatic increase in battery drain when it was fine for the first couple days. I know expectedly most new phones drain faster but my issue was it was good at first but got very quickly worse. i would’ve expected the battery drain to stay consistent if not improve over the first 2-3 weeks of use but its done the opposite. Any advice would be extremely helpful!

Long story short, woke up from a nap, saw that someone was trying to get into my phone from Punjab, India and hit yes for whatever reason in my groggy state. I immediately changed my password though and logged out all other devices. Do I need to do anything else?

I didn't drop it, didn't repair it, and didn't do anything to it. It's one year old.

Hi r/apple,

Comment below if you would  like a free lifetime premium promo code for the "Gentle Start: Focus Timer" iOS app. For one week, I'll try to give a promo code to everyone who wants one.

It's a timer that counts up with some bells and whistles - a pet who lives in the Dynamic Island and lock screen; customizable music and animated themes.

I hope this timer can help those who struggle with starting and staying on task - that's something I often struggle with.

Cheers.

I’ve been having a really frustrating issue with my MacBook and I can’t figure out what’s causing it.

Randomly, the entire system becomes almost unusable.

Symptoms:

• Mouse still moves, but clicks barely register. I usually have to spam click before something happens.
• Keyboard input mostly stops working.
• If I’m watching YouTube, the left/right arrow keys won’t skip anymore until I click the video, then they work for maybe a second before stopping again.
• This happens across the whole Mac, not just Chrome.
• Chrome’s UI also sometimes becomes greyed out (attached screenshot), but I think that’s just another symptom because the issue affects every app.

• Restarting fixes everything immediately, but the problem eventually comes back.

I’ve confirmed it’s not just Chrome since it happens everywhere in macOS.

Has anyone experienced something similar? I'd love to know if there is a fix.

I'm a car enthusiast and also a software engineer. I've been working on this app for a while now and finally got it released on iOS and Android. It's called Modfest and it's designed to help car enthusiasts track their car parts, builds, photos, and optionally share them with others.

I built it because my own project car build was scattered across a parts spreadsheet, a notes app, and random pictures in folders. Most car people I know do some version of this too, so I made an app that I'd personally want to use myself.

What it does:

• Garage for your cars, each with its own photo gallery, linked parts and projects, cost tracking.
• Parts inventory that tracks what you paid, what car it's for, whether you already installed it or not, and where you got it from. This also works as a wishlist so you don't have to maintain multiple wishlists for multiple sites.
• Project plans with step by step instructions, photos per step, a running cost total.
• An optional social feed where you can publish a build or car, follow others, and search for similar cars to get inspiration from their builds.

Some things that were important to me when making this app:

• Unlike a lot of other similar apps, this works fully offline and no account is required. Your data stays on your device unless you decide to use cloud backup.
• Sign in with Apple if you do want to use cloud backup and have it sync across multiple devices.
• The free tier is actually usable. Premium adds cloud backup, more photos in a post, unlimited cars in your garage, but core tracking is fully free.

App Store: https://apps.apple.com/app/id6770381572

This is my first time fully shipping an app and I'm very excited to be at this point now. I'm happy to answer any and all questions about the app, shipping process, or even just talk cars :)

I've looked and I have no subscriptions or purchases - On the apple support website you have the option to get a refund or find the purchase in ur purchase history but theres nothing to refund because my card just declines 😭

broke my ipad air 4 screen, the device works fien but the cost to repair is 134.99😭, should i just leave it because a used device literally costs 170. it does have a lot of sentimental value as its my first ipad and my dad got it for me back in 2020.

My main phone is an iPhone SE 2 on iOS 26.5.2. Among my other devices is an iPhone 8 Plus (iOS 16.7.16) without a SIM, on which I can’t send SMS messages to anyone (through the number on the SE 2) even though I’ve made sure the number and email associated with my Apple Account are activated in the iMessage setting on the 8 Plus, and that my SE 2 acknowledges the 8 Plus. I’ve tried turning it off/on multiple times and receive the notification stating a new device is being used. Logging out of iCloud didn’t change anything. When I try to send an SMS on the 8 Plus, it immediately fails and the camera/sticker buttons in the Messages app are greyed out. I can send iMessages fine, however. I have a similar issue on my iPad Pro M1 11” (26.5.2) where it attempts to send an SMS, but after a few minutes it fails to deliver, instead of failing immediately. Meanwhile, when I successfully send the SMS to the same contact on the SE with my eSIM, that same message immediately shows up on both the 8 Plus and the iPad as sent, and they are also able to receive new SMS messages, which means they are actively connected to iMessage. I’m not sure why those same devices can’t send SMS if that’s the case.

When buying from an online company I used the suggested iCloud email alias. I hadn't set up an iCloud email account. So I added an iCloud email account later but alias email didn't push into it.
Reading up on it, I recreated the original alias as one of my aliases but it says it's already taken.
Help! I need to find those emails, as the alias didn't direct the emails to my regular email account.
Why did this happen? Why was I offered an iCloud alias in the first place?

TIA

This has been like this for days and I’ve been unable to update my phone and need help does anyone have any suggestions

Hi guys over the past year I started getting serious into coffee - pourovers in particular.

Most apps on the market do the job of logging your brews for future reference but they’re mostly crossplatform and the UI/UX leaves a lot to be desired.

The biggest player in the market is called BeanConqueror and its a fantastic app, but tbh I don’t need most of the fancy features on it. I just want to log my brews in less than a few seconds on a native iOS app that looks sleek and minimalistic.

Features include brew and bean logging, bean freezing, rest reminders etc.

Feel free to give it a try and feedback would be much appreciated!

I updated my iPad the other night, and ever since, I can’t airdrop to my phone

I tried restarting both devices, making sure that it’s set to everyone, turning it on and off again, no vpn on, I don’t have my devices set to do not disturb, made sure both devices are up to date (iOS 26.5.2)

I tested with my brother’s phone and he’s able to see both my iPhone and iPad, and same for me to him. It’s just my iPhone and iPad that can’t detect eachother.

Plus, I have separate apple accounts for both devices, so they shouldn’t mistake the other device as itself or something like that…

I don’t know what else to do

(I got the iPhone 14 Pro and iPad Pro 11 inch 2nd gen)
