    24" Early 09 iMac

    So, I have had this iMac in my ownership for a while and I finally got around to using it... In 2016 I purchased an early 09 iMac (24" with the 3.06 GHz CPU) with a graphics card issue. I discovered that adjusting the resolution to 720p can give better results by causing less strain on the GPU...

    AppleCare for iMac Worth It?

    I passed on AppleCare when buying my 2020 iMac. I can understand getting AppleCare for a MacBook as it gets bumped around a lot and prone to damage, but my iMac will, more or less, sit untouched. I got AppleCare for my last iMac (15,1) and I never had a reason to use it, so it turned out to be...

    iMac suddenly lagging for short periods of time, but very frequently. How can I diagnose the issue?

    2019 iMac 5K on 10.15.7. This started within the last week. I notice it primarily when my cursor starts to lag around the screen. Can't be an issue with the mouse because it happens with my trackpad as well (these are the official Magic Mouse/Trackpad). I've tried watching the Activity Monitor...

This is during non-gaming use, even while just web surfing, but more easily reproduced when doing things like viewing Google Maps in 3D. (Plus whatever macOS might be doing...
