Trim Enabler Ssd Mac OS X System
Now you can also increase durability.Last winter I outfitted my old Mac Pro with 3 EVO 850s, and an OWC Accelsior E2 PCIe blade, all 1 TB. It can enable TRIM on non Apple-branded disks. Driver) and turning off kext signing isn't something I feel comfortable doing (for system security reasons) but you may not have an issue with it.Chameleon is an optimization tool for Solid State Drive on Mac OS X system. A kext is a kernel extension (i.e. In order to use TRIM Enabler to enable TRIM on your non-Apple SSD in Yosemite, you have to disable kext signing before the utility can enable TRIM.
I have the startup/system drive, my DP projects drive, and a library/sample drive.So the second part of my question is, how do I trim enable all the volumes, not just the startup drive? The Terminal command line to enable trim that we see out there is always for the startup drive, I've never found how to do non-startup volumes? Or does it turn it on for all SSDs at once? I'm running OS Sierra.I've seen arguments here about the necessity of enabling trim or not. But the EVOs absolutely did need to have trim enabled. I definitely don't want to wear out the performance of the drives, but I wonder if it's too late to turn trim on? Would I potentially mess things up? And if it's not too late, would it even be beneficial? The E2 blade is an OWC product and they claim that it's not necessary to enable trim for their SSDs, but I have to confirm that with them tomorrow. I was actually advised not to by the store guy, because there were problems with the EVOs (turned out it wasn't really an issue with Macs, but I bought his story). Uninstall Apps With Ease The intelligent Uninstaller feature will find any apps hiding on Mac and help you uninstall them properly, leaving no helper tools or other leftover files behind.I did not enable trim on these.
She did not have trim enabled when she used it in the MacBook Pro, because the OWC guy said not necessary. (PS: You might want to add your OS version to your signature.)Edited to reflect "Disc First Aid" as proper tab reference in Disc Utility program.Mikehalloran wrote:Likewise never engage Secure Erase or Write to Zeros (Disk Utility won’t do that anymore, either).I went to repurpose my wife's old laptop drive, a 480GB OWC Extreme, as a work drive on our video computer. Only your boot drive requires running from Recovery or alternate boot drive to effect Trim.Also run Disc Utility > Repair Disc for all your other SSDs (from Recovery or from normally booted Mac) to bring the Trim state up to date.You should then be good to go, as Trim will now be an ongoing process for all drives, including your boot drive.Hope this helps. As the process is nearing completion, you should see a note along the lines of "Trimmed Free Blocks".If running an older, pre Recovery Partition OS version, you can access Disc Utility while booted from an alternate boot drive. I've already determined that I should have enabled it initially.Assuming you are running Safari, after you enable Trim as Mike describes, restart your Mac from macOS Recovery and run Disc Utility > Disc First Aid, on your system drive as described here:Click the "Details" toggle to show you what is happening as the process proceeds. It's to determine if I can still turn it on, after the fact, and if it will do me any good to do so.
Maybe it would last until the warranty expires.I really appreciate all the info guys! I do have one other sticky question:That video computer I mentioned is an iMac with Apple's hybrid drive. Write to Zeros.From what I've read here, I realize my suspicions were correct- he was trying to get me to get the drive back up to speed, at the expense of its lifespan. The drive is still under warranty, but he told me to first try a low level format, i.e. I called OWC, talked to the tech guy. The read speed was fine, but the write speed was less than half what it should be.
If, however, there's a non-APFS drive or partition in the system, Command-R will boot into it instead (and you won't be able to see any APFS volumes). You can run it to trim an attached non-APFS volume, however.Option-boot does not bring up the Repair Partition on an APFS drive — only Command-R can. Think of it as a virtual disk and you won't far off.Running Repair Disk from Disk Utility from APFS will not TRIM Unused Blocks on an APFS volume. If Disk Utility is run from 10.13 to an older SSD without APFS, it will TRIM that drive.Well there is one but things are different in OS 10.13 with APFS:When booted into non-APFS drives or partitions, you cannot see APFS volumes or partitions.There is a Repair Partition in 10.13 but it is actually an APFS Container. Is it OK use the Force Trim line in the Terminal and get those Samsungs onboard?And, would I want to run that line with every new SSD drive I get for that TB dock? Actually, that question applies to a new non-boot SSD drive for any machine.Mikehalloran wrote: It doesn’t work in High Sierra since there is no Repair Disk. Via a Thunderbolt dock (bare drives), I have 2 EVO 850s, and when I examine them in System Report, TRIM is not enabled.
There is no need to run it manually which is also true for El Cap and Sierra. If you get into trouble, you can Option Boot or Command R into the Repair Partition of the non APFS partition only (my El Cap drive is on eSATA and I can turn it off to Command R into my High Sierra Repair Partition).So what about TRIM? It works automatically on APFS drives and those attached if you enabled trimforce in Terminal.
