Greeting all....First time poster, long time reader.
I also have this issue of slow booting after upgrade. But here is the thing...
My wife and I both have Late 2016 MacBook Pro's purchased at the same time though Apple...
MacBook Pro (15-inch, Late 2016)
2.7 GHz Intel Core i7 - 16 GB 2133 MHz LPDDR3
1TB Drive
FileVault is OFF
...and we are running the same OS... 10.13.1 (17B48)
More or less the machines are set up the same way software wise other than I have Final Cut Pro X. (I have no large files on the drive however as I archive them off when done editing. My drive shows 155 gigs used of the 1TB at this time.)
YET...Her's boots in 19 seconds and mine takes 45.
I have tried...
- Running First Aid in the Disk Utility on the drive.
- Turning TRIM OFF and booted and then put it back ON. (No change either way but I am not sure it can even be turned off on these machines.)
- Resetting NVRAM (Option, Command, R and P at power up.)
- Removed everything under my account from Login Items.
- Booting into safe mode and then re-starting again. (To reset cache or something I guess.)
- Installing 10.13.1 over the top again just for kicks. (Man does that take a long time.)
I am still in the same position at 45 seconds to boot. My next move would be to try a complete wipe and install and then booting clean to see what happens. Then recover from TimeMachine my data etc. But from what I have read, people whom have done this are no better off other than waisting a lot of time. (Which it does take SO MUCH TIME even though these have the really fast processors and what should be very, very fast drives. It is amazing how long it takes.)
When I boot, the bar does not move very quickly, then it pauses for some time, then a slight flash in the display and then the bar moves fast and login shows up.
So, has then been any answer to this? Anything else I can try other than a full wipe?
Side note: I also seem to now have a graphic card issue where it does not clean RAM correctly and I will have something like an icon just stuck in the display that is over the top of everything until I reboot. Has happened 3 times.
Thank you kindly.
