Flyinace2000 Posted October 6, 2017 Share Posted October 6, 2017 Z87-UD5H 4700k 16Gb Ram Samsung 840 SSD nVidia 780 (using nVidia web graphic) recently upgraded to 10.13 and my somewhat slow boot got a lot worse. Here is a video of booting w/ -V https://photos.app.goo.gl/iMcTZZhaX1gbNjGQ2 I've attached my clover folder for review.

chriz74 Posted October 6, 2017 Share Posted October 6, 2017 hello, this is not an hackintosh problem. I have a real MacMini late 2014, the middle one 2.6Ghz. I also have an 840 evo SSD on that and the boot takes 47 seconds if TRIM is enabled. Verbose boot shows many pauses in the first stage. I also have an hack with 840 EVO but I got the 10.13.1 beta and the boot is slow too but somewhat a little faster than the Mac Mini. You could disable TRIM, boot will be faster although it should be the exact contrary: http://www.tomshardware.com/reviews/samsung-840-evo-msata-review,3716-10.html Link to comment https://www.insanelymac.com/forum/topic/328084-slow-boot/#findComment-2509667 Share on other sites More sharing options...
Flyinace2000 Posted October 6, 2017 Author Share Posted October 6, 2017 Yeah disabling TRIM made things book very quickly. Is it "ok" to use the SSD w/o TRIM? Link to comment https://www.insanelymac.com/forum/topic/328084-slow-boot/#findComment-2509810 Share on other sites More sharing options...

chriz74 Posted October 10, 2017 Share Posted October 10, 2017 Today I made a backup with time machine and restored it on the disk. The boot is 20 seconds faster now.

wasabicoder Posted October 11, 2017 Share Posted October 11, 2017 Are you on APFS? I saw these slow boot issues go away when I switched back to JHFS+. But I'm on High Sierra with Samsung 960 Pro m.2 so it could be a nvme issue for me. Interestingly, my boot times on APFS started out OK but progressively got worse and worse the more full my drive became. At 50% full it would take 5 minutes to boot. Switched back to JHFS+ with the same drive contents and my hack boots in under 5 seconds.

chriz74 Posted October 11, 2017 Share Posted October 11, 2017 Yes I'm on APFS. After restoring the backup to disk TRIM was already enabled. So now I am on APFS + TRIM and the boot takes 26 seconds while it was taking 48 before this process. The disk is an 840 evo 250gb. The pc is a macmini late 2014 (real). I have to try this on a desktop hack I have with OCZ vertex 3 60Gb Link to comment https://www.insanelymac.com/forum/topic/328084-slow-boot/#findComment-2513428 Share on other sites More sharing options...
chriz74 Posted October 12, 2017 Share Posted October 12, 2017 More evidence TRIM is not the problem. I just created a time machine backup for ASUS P8H67-V based hack and restored to the SSD. Boot was 58 seconds now it's 27 seconds. TRIM is enabled. It must be some mess HS is doing during HFS to APFS conversion when upgrading from Sierra.
