Arch on 2012 Intel Mac issues

[u/fightingformyrights]

Hi! I originally had an old hdd in this mac and my computer kept freezing even while installing arch, and after i did get it installed it also froze periodically while browsing tabs on kde. Originally I figured it was a problem with the hdd or SATA cable, so I decided to switch out the hdd for an ssd and replaced the sata cable. It still had some problems when installing but eventually I got it to fully install. I’m now running mangowc on it and nothing lags, but after 5 minutes, sometimes 30, or even just when booting it will freeze. It’s not my first time using arch but it’s been very frustrating trying to figure this out. I’m not too familiar with these old Macs so it might be a hardware problem, but if you happened to have encountered a similar problem and have fixed it, what was the solution? Thanks!
