[FEATURE] Add Installer Option to disable TRIM
PeterBurner opened this issue · comments
Description
After upgrading to macOS Monterey I was experiencing very long boot times (4min+). After some digging I found that macOS Monterey has problems with the TRIM functionality of my Samsung NVMe SSD (Samsung 970 EVO Plus 500GB).
I found some threads in different forums that suggested to disable the TRIM functionality. For me this helped bring down the boot time by a lot.
Suggestion
- Update OpenCore to >= 0.7.9
- Add installer option to set
Kernel > Quirks > SetApfsTrimTimeoutto0
Environment:
- Running OSX version: 12.3.1 (21E258)
- HaC Mini installer version: 3.1.5
Additional context
From OpenCore 0.7.9 release notes:
Added new method to disable trim when SetApfsTrimTimeout is set to zero
I also have the problem of a significantly increased boot time since upgrading to macOS Monterey. And I also have a Samsung 970 EVO.
Turning off TRIM to get normal boot times sounds great, but aren't there (significant) downsides to doing so? A quick web search suggested, that it may decrease the life time of your SSD.
@StSiem I have the same concern. However the question is, does TRIM work in the first place? As far as I understand it the TRIM command does not work properly and runs into a timeout. After that delay the boot process continues. So there would be no difference in SSD lifetime if we disable TRIM.
I am no expert on this. @osy feel free to correct me.
Either way its probably best to replace the SSD with a supported model if one is able to do so (I am currently not).
It would be interesting to know if users with other SSD models and TRIM enabled are also affected by the long boot time 🤔
If someone is looking for a replacement SSD, the issue I linked above contains a list of compatible models.
Ah perfect. Thank you for the link.

Does your drive already use the latest firmware?
According to Samsung Magician it does!
Well I did some research - and it is a mess....
First thing – it seems Apple drivers work best with Phison Controllers (i.e. used in WD Black drives or Crucial) and doesn’t work very well with the Controllers used by Samsung (Phoenixs) – Samsung made a Firmware Update to the 970 EVO Plus in 2019 that gave support for MacOS wich broke with Apples NVME implementation in Monterey…
The next bad thing is that Samsung changed the Controllers to from Phoenix to Elpin in late 2021 and we most probably won’t see any more Firmware Updates for the older drives…
And some people report success with newer Elpin drives with latest Firmware – but I am not too sure about it…
To add more bad while WD Black drives seem to work fine they are actually slower than the Samsung drives – but of course still much faster when working with working TRIM support with Monterey than the broken Driver support with Samsung drives…
tl;dr
Deactivating TIRM is only a stopgap solutions.
Right now the only “real” solution is to use something like WD Black 750 or 550 instead - just odered some...

@Medizinmann-MD
This means that an NVMe drive from Samsung with updated firmware (let's say Samsung 980 PRO) should work on Big Sur?
Thank you!

Well - AFAIK Big Sur should work fine with 970 EVO and 970 EVO Plus with the latest firmware update (see https://dortania.github.io/Anti-Hackintosh-Buyers-Guide/Storage.html).
With the 980 Pro even some people report success with Monterey - but Ia m not so sure about that - I don't have very reliable sources here....
After using a Samsung 970 I switched to a WD Black and can confirm, that the boot is much quicker now
I have the same problem, but the Kingston nvme SSD.
Thanks @osy!
I installed your test version on top of the latest HaCMini release. I selected SetNoTrim in the setup wizard.
I can confirm that my Hackintosh still boots properly and that the boot time is greatly reduced like when setting SetApfsTrimTimeout manually.
Many thanks for your effort!
