Installed 2020-005 to 2010 Mac Mini 4,1 HDD APFS external volume (no such problem with same update to Late '09 iMac 10,1. APFS HDD external.
As usual after a secupd to this Mini (has occurred after last several secupdates), hangs, freezes, black screen, innumerable delays, constant beachballing, desktop not loading.
After Desktop finally appears, can wait 15 min before something decides to open, then another 10 minutes before it responds to input. Have done numerous restarts, ran the patcher 1.3.7 maybe 4 times. No way to run Onyx, at least for the time being, as I would probably fall asleep before it loaded and responded, as things are.
Drive appears to be fine, as I also run High Sierra on the internal and externals with zero issues.
Ran DU on the APFS volume in question and was rather alarmed upon seeing
Code:
warning:inode_val:object (oid 0x1e9fd) : invalid internal_flags (0x2800)
However, crossed my mind to run DU on the iMac APFS external where there are no issues, and got the exact same output. So it seems that this warning, such as it is, may just be a side effect of the patcher??? (Or, since I ran DU from High Sierra, not Mojave, could there be some kind of dissonance between the 2 DUs producing this message? Will try running DU from Mojave to the Mojave volume in question.) As when DU finishes, it reports "Drive appears to be OK"
EDIT: Dismissing the results from DU, as just ran DU from Mojave to updated Mojave volume at iMac. Didn't get that warning. So this would appear to be the result of running High Sierra DU for Mojave volume.
DU messsages apart, bascially don't understand why I always have such issues with updates on the Mini -- not as powerful CPU as the iMac, to be sure --but still doesn't explain all these problems.
