![]() ![]() Updated Power save settings - no more issues:Ĭrash/reboot issue no longer occurs after waking up the display.Ĭonclusion: the issue is clearly coming from the Mac mini resuming from sleep mode since it no longer happens with the updated settings that doesn't put the Mac mini to sleep mode. I have an Apple Thunderbolt display and HDMI monitor attached to it.Ĭhanging the power saving option solves the issue but I don't want to continue using this "workaround" for my Mac mini.Ĭrash/reboot issue occurs after waking up the computer from sleep mode. I'm having this issue with my Mac mini (late 2012) Quad-Core Intel Core i7 2,3 GHz running MacOS Catalina v10.15.7. I dislike Windows generally but I spent 800$ for this machine - Windows isn’t that hard to use! ![]() I suspect that that they merely applying a formula with regard to basic common elements( like does the computer use DDR3, is it an Intel chip based machine, can it support adequate graphics and so on.) I also think that they have upgraded my firmware incorrectly. I doubt very much that Apple is going through the process of dragging out older Macs and testing their newer systems on them one at a time. I had some problems after installing High Sierra a few months ago and I believe that Apple is inadvertently damaging computers which it says are compatible to it’s new systems but is not. I tried everything from replacing CR 2032 battery, to changing my graphics card, to pushing all sorts of button combinations, testing my Power supply - it was working fine, to taking out the CR2032 and letting the computer sit without power for 48 hours( which has worked for me before on earlier towers and MacBookPro, lately.Īs a last resort I put in a Windows 10 hard drive( having seen a couple of Mac Book Pros using Windows 10) and I am happy to report my Mac is working perfectly. After installing Mac Mojave my computer kept restarting then not starting. I have a Mac Pro tower mid 2011, Xeon two quad cores. Now reboots often on return from sleep and boots 2-3 times on fresh start from shutdown before eventually reaching log-in screen I did have one of my two 2TB Seagate FireCuda go bad a few months ago - maxing out its bad sectors allocation - so I replaced it with a Samsung EVO SSD 1TB - which I was used first as the primary boot drive - but when this rebooting behaviour began - subsequently trying to isolate causes I have created a Fusion Drive out of the 1TB SSD and the other Seagate 2TB HD - with a fresh install of 10.13.6 ![]() I cannot identify what change may have triggered these rebooting cycles, apart from some incremental updates from Apple, as I've been running High Sierra on this machine for a long time now without other problems. On my maxed out Macmini mid 2011 i7 2.7 GHz I also have this problem its only manifest itself in the last 6-8 weeks or so ![]()
