trim

I am wondering, whether I need to set TRIM manually on Macs I have upgraded from having hard drives to SSDs? I know that at least several years ago, this was not automatically turned on. With the later APFS-based version of macOS, however, will TRIM be enabled on SSDs automatically?

Hi Guys, as you can see the USB-C charging cable comes with the iPad is way too short, I try to use my MacBook Air charging cable, however due to my iPad case ports cut out issue, the cable will not push all the way into the iPad. So I decided to trim off the white plastic part at one end of...

Some folks have noticed that the black trim piece underneath the display is "wavy" or appears to not be glued properly. Looks like the display cables the run underneath this trim piece are causing it to be wavy. iFixit provides a better view...

I have installed a Samsung 870 QVO in my 2008 MacBook Pro. Then I've installed Catalina 10.15.7 with dosdude's patcher and then installed my time mahine backup. The problem is, that the system crashes and restarts every time I try to wake it up from sleep mode. I have noticed that TRIM was...

Hello. I'd like to know if it was possible to enable TRIM for a specific external SSD on an M1 mac (specifically a mac mini M1 2020 with macOS Big Sur 11.3). Even a paid app would be good; Basically I'd like to avoid the onboard SSD of the mac being affected. Thank you very much.

I picked up a 500GB SSD for my Early 2011 MacBook Pro and upgraded to High Sierra, which reformatted the SSD to APFS. I plan to not completely fill my disk and keep the usage under 80%. I’ve read many posts on how enabling trim has caused slow boot times and performance in APFS. Is that still...

How can i know if trim is enabled on my OS?

Hi, I want to cut/trim the commercials out of .ts and .mp4 files that I have DVR'd. It needs to be smart (only re-encoding the frames between the cut-point and the next key-frame). The closest that I can find that meets this criteria is: SmartCutter - but it crashes (costs £ 50 but has not...

Hi, is here a discussion about this already? I have a WD ssd in external case and Disk Utility tells that the type is "Disk" (not "Solid State"). Is there a reason to think about trim command? Is there external ssd's that are identified right? System Information tells, that my case is: VLI...

I have been using sudo trimforce enable to use trim on my SSDs on my 5,1. I disabled SIP to make few changes and had left it there. When I did a status check trim was disabled. repeating the command multiple times did not enable it. Booting from other partitions (High Sierra, Mohave 1014.1)...

In the past, I could verify SSD TRIM status by reviewing the SATA/SATA Express line in the system information feature. On my Macbook Air 2018, it says, "This computer doesn't contain any serial ATA devices." On the storage line, it says I have an Apple APFS Media SSD PCI-Express but nothing...

I was under the (mis?)impression that under Mojave, TRIM was supported for external SSDs connected via Thunderbolt. I have a 2015 27" iMac running 10.14.3, with a Thunderbolt 2 enclosure with a Samsung 850 EVO SSD. System report says that TRIM is NOT supported. Is there something I need to do...

Hey everyone... I'm seeing some weird storage issues on a new MacBook Pro I bought in September. I deleted 100+ GBs of data last week. Checked space the next day and noticed the numbers didn't seem right... So, I decided to before/after screenshot what Disk Utility was reporting as free space...

My last system SSD died after two years of heavy use. Some reports indicate that overprovisioning has benefits. But it seems like as long as trim is enabled and the drive is left with a lot of free space the same impact is achieved. I am using dual MX500 2TB for system and data formatted APFS...

So as not to muddy the New BootROM 138.0.0.0.0... thread w/ more of this offshoot, I hoped I might solicit some advice about this TRIM issue in a new thread. Basically, I have a pair of SSUBX 512GB blades in a RAID1 mirror in a server. The read speed after the firmware update (and using Slots 2...

Hi all (apologies if this should go into another subgroup - please move if you please). I‘m about to receive a 2017 iMac 27 with 512SSD (yeah!). Well, I wanted to expand it with an Atiko 2x 2.5 drive (?) external enclosure that connects via Thunderbolt2 using two Samsung 512GB SSDs (850 EVO I...

Hi fellow Mac OS X user, I am running Lion (10.7.5) on a mid-2011 Mac mini which boots from an extended (journaled, encrypted) partition residing on a Crucial SSD. When I tried to upgrade to El-Capitan, the system could not boot during the installation process, and I was greeted with an icon of...

Super weird issue going on. Upgraded my 13" 2011 MBP with a Samsung 840 Pro SSD to High Sierra. (Automatically upgraded to APFS with TRIM enabled) Last night it wouldn't boot showing only a flashing folder/question mark. Did all of the usual stuff PRAM, Recovery Mode, repaired permissions, etc...

Let's try make a report here with make and models of the SSDs affected by boot and r/w slow downs. I have a 256Gb 840 EVO. HS w/ supplemental update and trim enabled takes 47 seconds from chime to desktop (auto login). I will add the time later with TRIM disabled. Macmini late 2014 2.6Ghz.

I have a iMac 27, 3.4 late 2013 standard model and I want to make it better by booting from an external SSD disk via TB2. Now SSD speeds of 500MB/s would be ok but if it would be possible I would like using something like RAID 0 in order to get higher speeds (or maybe you know other solutions...
