Question: MacBook Pro insanely slow after reboot

I've just rebooted my Macbook Pro mid 2012 and I've done a factory reset due to some problems before. I reinstalled el Capitan (which took all night to download) and now it took me so long just to set up a user account. Even when I type a letter the rainbow wheel appears and I have to wait.


Things I've done:

-Repaired disk (everything was fine)

-Done the PRAM thing

-Tried booting into safe mode but it's still very slow.

-Tried restarting

-Reinstalled OS


This should be naturally fast since I've installed an SSD inside, however as I was updating to High Sierra my laptop died due to me being away from it and the extension of the charger was taken. As I tried to restart the download I have experienced insane lag.

MacBook Pro, OS X Mountain Lion (10.8.5)

  • Select a problem from the drop-down menu to enable the "Start EtreCheck" button. Optionally, you can add comments on what issues your Mac is experiencing, especially to aide others with similar Mac issues.
  • Click on Start EtreCheck
  • Allow the program to run to completion.
  • When done, select Report from the left-side window to display it.

Though far from the only cause, one of the triggers for Really Slow is failing HDD or SSD storage, or a failing storage controller. There can be other problems with the hardware, as well. If you don't have complete and current backups of all of your MacBook Pro data, then getting current and complete backups of all of your data is your first and most important task. Then once those backups are available and as was quite correctly suggested earlier, please post up the output of the Etrecheck tool.

Based on the Etrecheck report, You're very low on physical memory, as a starting point. That system model can usually unofficially be configured with a maximum of 16 GB of memory, and a maximum of 8 GB of memory per Apple. That system accepts two 204-pin PC3-12800 (1600 MHz) DDR3 SO-DIMM sticks.


I'd also see if Samsung has any diagnostics available for that specific SSD, and run those. (Not having TRIM support or having TRIM support disabled can make SSD writes very slow, too.)


I'd also disconnect all external devices from USB and FireWire as a test, as those can sometimes effect performance.

The 2 places I’ve seen recommended most to buy reliable RAM are below. I have purchased RAM several times, a MacBook Pro battery, and a hard drive from Other World Computing and have always been very satisfied with the product and service. They have on-line instructions on how to replace the RAM. OWC has also tested RAM above what Apple states is the maximum. I had 6GB installed on an early 2008 iMac supposedly limited to 4 GB and noticed an improvement.

Lack of TRIM slows SSD writes. SSD writes to prepared storage are pretty fast, but erasing and preparing the sectors for write is very slow. TRIM moves that initialization process from when the data is written to the sectors to when the sectors are released such as when files are deleted, and which allows the SSD to perform what is slow work ahead of the need for the storage and to cache sectors that have been prepared for writing. This rather than initializing and writing right when the SSD sector is needed. (Internally, SSD storage sector activity and the usual wear-leveling-related and TRIM-related sector writing, mapping and remapping activity is substantially different from that performed on typical HDD storage.)


Lack of RAM slows system performance, as it means reduces the amount of app data and code that can be cached. As fast as SSDs are, they’re still slower than reading and writing data to RAM. When there is no free RAM available, macOS has to flush the data caches and (if the data is subsequently needed again) go get that data from HDD or SSD storage (or regenerate it), or has to swap the existing contents of RAM back out to HDD or SSD to free up enough RAM for what’s now needed.


All that written, I’d wonder if that SSD is just really slow due to lack of TRIM, or a due to an SSD or due to a hardware problem.


Your system is presently populating the Spotlight caches, which means there’s a whole lot of I/O happening. As a test, you could temporarily disable Spotlight, and see if performance improves.


You’re also headed for enabling TRIM and possibly for a diagnostic disk swap, to try to determine if there is an issue with that SSD. And clean off the entire external USB and FireWire, and see if performance improves as sometimes activity involving or errors with other I/O devices or with the cabling can effect system performance.

I see.

Apple currently have my MacBook. They too were puzzled about this whole situation. I'll most likely get the results this week. Hopefully it's nothing major and too expensive.
