should I change something in hibernation?
I'm waiting for the adapter and sabrent blue ssd to be at home from Amazon, I'm currently on the lastest catalina with 189.0.0.0 bootrom on early 2015 MBP 13" and I did a time machine backup. Can I restore the time machine backup on the new ssd? I've made a usb disk of catalina just in casei have an early 2015 MBP 13" with sabrent 1TB/short sintech adapter, no hibernation issues here, no battery drain during sleep, bootroom ver. 189.0.0.0.
Sure can. I did the same thing this past weekend.I'm waiting for the adapter and sabrent blue ssd to be at home from Amazon, I'm currently on the lastest catalina with 189.0.0.0 bootrom on early 2015 MBP 13" and I did a time machine backup.

Hello everyone, first post and first question.
I don't remember where I read this but wasn't the Sabrent Rocket's controller changed recently? IIRC the argument was due to the controller change it's not as good as it once was.
I'm trying to narrow down my choices. So far I'm considering the Adata SX8200 Pro or the Sabrent Rocket but I haven't read all 241 pages yet so I'm open to suggestions.

Yes, but you would need to extract the bootrom update from the os update and use an efi programmer.
It may be simpler to have a local Mac repair shop flash it for you.

So if I go in an authorized apple repair center and ask them to flash a new bootrom / efi they will do it ? Just asking cause I went earlier and I may have been quite tired as I was asking them to update my recovery instead of bootrom and they didn't really understand. The guy insisted that the recovery updates itself by pressing cmt alt r ... And at that moment I just assumed he had no idea what I was talking about.
I wouldn't rely on that, especially an authorized repair center. You could just buy a cheap 128gb one for updating the bootrom if you don't already have an OEM drive.
Well my OEM is broken. I have another macbook air from 2019 but I have to check if the ssd matches mine. Let's assume I manage to get an OEM drive. If I have catalina on it, will the bootrom update itself as soon as the drive is connected ? Or are there any other steps to follow ? Thanks for the quick answer btw.
I think the MacBook Airs from 2018 and on have soldered SSD's so that won't be an option. A 128gb OEM drive is under $50 on eBay.
And no I don't believe the bootrom will just update itself. I think you need to run a system update that includes a bootrom update while the drive is connected. Some users are reporting the bootrom will update with an NVME from High Sierra on, so you should probably just keep an eye on it for now and see if that happens in your case.
Thanks ! I've just read the guide from cmd-q listed in this thread and I will maybe try this weekend to update the bootrom. Meanwhile I managed to run Mojave from an usb with the Mojave patcher.

Also any other AHCI ssd that I can use with this macbook pro retina mid 2014 besides the owc in order to avoid all the firmware update process ?
I don't believe the OWC one is capable of doing it. I think they advertised the latest Aura as being capable when it first came out last year but then they retracted that. You may be able to take the OEM Apple 128gb and stick it in the OWC Envoy Pro and boot from that, run updates, and I think it will update the bootrom, but nobody has confirmed for me that booting from an OEM Apple SSD via USB and running updates will also update the bootrom.
Like I said though, I wouldn't worry about any of this if I were until you actually confirm the bootrom is or isn't updating. And if it's not updating, if I were you, I would just get the 128gb OEM drive and slap it in there once a year to run updates. Your MBP is from 2014 and they will only be updating it through 2021.
Seems legit, might just leave it run from usb for now and hope the new macbook pro will be different from the latest models (I'm typing from a butterfly keyboard atm and it's just yikes). Anyway thanks for the time taken. Hope this will help other people stuck with this problem.
I just went through your post history and saw that you think it wasn't updating the bootrom prior to the SSD going bad. Sorry, I didn't get that part till just now. What is your bootrom version? I only see you mention that it's "Yosemite" but you don't give the actual number.
I assumed it's stuck on Yosemite as it was the 1st os to install when I went into recovery.
Well it says 157.0.0.0.0 (Guess it's Catalina one). Altho I'm running from an usb atm thus I have no idea if the value is biased or not.
Nevertheless, the SMC version is 2.16f68 (this is the one from yosemite iirc)
What about SMC versions?
Isn’t EFI firmware complex enough for you? There is currently no way to check the integrity of other firmware, etc., and no one has even started to focus on SMC versions.
I've never had to use the recovery partition so I'm not entirely sure how it works, but it could have been messed up since Yosemite so it was never updating with the rest of your computer. I see threads about this being a thing.
Your bootrom is up-to-date so you should have no issue installing Catalina on your Samsung drive. Just get that done and don't worry about the bootrom version. If your MBP is running fine then just check in a year or so from now what the latest bootrom for your model is and if your bootrom version has increased from what it's at now. Even if it hasn't I wouldn't worry about it if your system is running fine. "If it ain't broke don't fix it."
As for the SMC, if you google that version number, you see many people using versions much later than Yosemite with that SMC version. Same goes for my SMC version on my 2015 MBP. Nobody is even keeping track of SMC versions on the internet so I wouldn't even worry about it. I can't even tell if they're really updating it, and nobody else really can either:

Yeah I've got lost a bit with all the different firmwares. Thought smc should match the bootrom. Anyway if the bootrom is updated I still don't get why the Samsung drive is still not recognised in disk utility.
Question: Do you think a new battery will get me up to at least 6hrs ?
