Here's a few important tidbits I had to figure out for myself and no guides covered:
- IMPORTANT: before you do anything, update your mac OS to get the latest security updates, etc. on your old drive, so that it has the latest version. 100% do this. You cannot restore your time machine backup with two different mac OS versions. IF you're jumping to an entirely new version (say, Sierra to High Sierra, and you're up to date on security patches for Sierra), you don't have to go that far and it'll actually save you time.
- get out your external backup and make a full time machine backup (disable your automatic sleep mode in settings, or this will get interrupted and you'll have to start over!... restore couldn't put the three different pieces of my backup back together again. it was humptied.) You can use any external backup for this, as long as you format it ExFAT with your disk utility. !!Formatting will wipe the external backup disk, so make sure you have everything off of it, first.
- making a time machine backup is going to take HOURS, so do it either during the day or over night and leave your laptop ON and plugged in (again, no sleep mode and don't close the lid). You can turn the screen and keyboard off, though.
- there are many of format options for the drive in OS X, and you have to use a very specific one. when you format the drive using disk utility, there are two drop downs. You want the 'GUID partition map' from the first drop down, and 'OS X Journaled ' from the second drop down. If you don't do that correctly, you won't be able to install the OS and restore time machine backup to the new drive.
- you then will need to install Mac OS X using the restore utility (safe mode with the list of options you used to get to disk utility in the first place. just reboot and do the same keys as before after you've formatted the drive)
- you then need to update your mac OS to the exact same version you used to make the time machine backup (go back to the first thing I said. this is why.) If you got your mac with lion and you're on High Sierra, you will need to go through the process of updating alllllll the way to High Sierra again.
- then you can restore your time machine backup to the new disk
- don't worry about de-registering your device on iTunes/iCloud. Since you're using a time machine backup to restore everything, it'll be considered the same device by apple.
- NOW if your OS is STILL out of date after you've restored because you wanted to save time, update your crap. There was a major security patch in the last few months as of the time that I'm writing this (to areas of mac OS that have been around a LONG time) and you'll want to make sure you have it.
You will have to erase the drive and set it up as GUID Partition.
Quick tip to save you hours... make sure you take a complete time machine backup, do the install of the OS through recovery but do not restore from Time machine before the OS is installed. If your recovery OS doesn't match your Time Machine backup OS, then it will throw an error during the process.
Few hours later, successfully restored.
Now for the SSD... I did not see anywhere close to 950MBps... the most I have seen is 450-700-ish max. I am running on an Early 2015 MBP 13" i7.
I have noticed excessive battery drain after this install. Battery lasts only 2hours or so now while on my OEM ssd, it used to give me 5-6 hours easily. I tried doing all the trouble shooting methods mentioned online.. resetting PRAM, NVRAM..etc etc... still no change.
So if you want an upgrade with excessive battery drain.. then this is for you!
Edit: Replaced OEM 128GB SSD and the battery life is fine now. Both of them run with seemingly the same Amp and Voltage... but for some reason the Transcend consumes more.
Wouldn't recommend this drive. Spend $100 more and get the OEM 512GB.
I upgraded from the 512GB Apple SSD and LOVE the extra space, enabling me to leave (sell) my external drives at home.
No noticeable change in battery life with this drive.
Formatted to APFS in High Sierra with little issue, required one reboot to see it finally pop up...started to panic when it wasn't there the first start-up.
I did have to manually partition and format the drive. When I told it to partition and format as part of the Time Machine restore, it failed almost right away.
What I didn't realize is that Apple puts a recovery partition in the firmware in newer MacBooks so you can restore your MacBook without finding OSX installation media. This is not a partition on the hard drive.
