Slow Mac Pro after complete reset and SSD upgrade

Hello all,

A few weeks ago my Mac (mid 2012) started to slow down, eventually I tok it in to the store for some guidance. The guy told me to run verify disk, repair disk etc, which I did but it didn't help. I then decided to gather the files I wanted to keep and reset my mac, still no better. I then tried to update to El Capitan, which only made matters worse. After hours of fiddling and waiting I eventually ended up back with Mountain Lion somehow.

I went back to the store where he then said that my hard drive had failed and it needed replacing, so I upgrades to a 250 GB Samsung SSD 850 evo. This made a slight improvement in that I managed to get El Capitan on to it now. However, the boot time is around 7-8 minutes, and any task is taking a ridiculous amount of time, I get the rainbow wheel very often - even though at this stage I have no software installed other than that downloaded as basic (other than Spotify) nor do I have any files on my hard drive either - again, other than those that come as default. I'd say that the performance hasn't improved a result of the hard drive change.

I'm getting pretty stuck now, my CPU usage seems to go up in peaks but there is no indication as to what is causing these peaks. I have disabled spotlight but that didn't help either.

Help please?

Hi Monkton:

If you are running El Capitan it supports Trim.

I am running a Samsung 500GB 850 EVO on an Early 2011 Macbook Pro, which is running very well. I have trim enabled.

To enable TRIM, first save all your open documents as this will reboot your Mac.

1) launch Terminal.

2) Type "sudo trimforce enable".

3) Confirm that you want to enable trim.

4) Reboot your Mac.

To verify that TRIM is enabled, click the Apple icon in the top left of your screen. Choose "About this Mac" -> "System Report" -> "SATA/SATA Express" and look for the entry "Trim Support". It should say "yes" if trim has been enabled.

Is the format alright? Its changed it from when I pasted it in..

El Capitan runs best on at least 8GB or RAM.

To upgrade memory in Macbook Pro:

OWC OWC memory or crucial Crusial Mac memory are good places to get memory.

See OWC Install Videos: OWC Install Videos

Hi Kim,

I have trim enabled, performnce seems to be slowly getting better. I will look in to upgrading my memory, however, the problem was still present with the previous OS (I can't remember the name).

Monkton

Was it always enabled, or did you just enable it.

Kim

Though El Capitan is best served by 8 GB RAM, Ram is not the problem currently based on the Etrecheck report.

Try a El Capitan combo update and see if there is any change:

Ciao.

I've had it enabled since this morning, so not very long.  - before you comment. Performance is slow whilst running, however boot up time currently at 15 seconds or so.

Well boot up time has gotten a lot better.

Have you tried the following:

Try reseting the PRAM: Reset the PRAM

And try reseting the SMC: Reset the SMC

See if that helps.

When you see a beachball cursor or the slowness is especially bad, note the exact time: hour, minute, second.  

These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.

Launch the Console application in any one of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad and start typing the name.

The title of the Console window should be All Messages. If it isn't, select

          SYSTEM LOG QUERIES ▹ All Messages

from the log list on the left. If you don't see that list, select

          View ▹ Show Log List

from the menu bar at the top of the screen.

Each message in the log begins with the date and time when it was entered. Scroll back to the time you noted above.

Select the messages entered from then until the end of the episode, or until they start to repeat, whichever comes first.

Copy the messages to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.

The log contains a vast amount of information, almost all of it useless for solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.

Please don't indiscriminately dump thousands of lines from the log into this discussion.

Please don't post screenshots of log messages—post the text.

Some private information, such as your name, may appear in the log. Anonymize before posting.

When you post the log extract, you might see an error message on the web page: "You have included content in your post that is not permitted," or "The message contains invalid characters." That's a bug in the forum software. Please post the text on Pastebin, then post a link here to the page you created.

If you have an account on Pastebin, please don't select Private from the Paste Exposure menu on the page, because then no one but you will be able to see it.

Hi Linc,

Thank youufor yo detailed instructions.

I have done so, one task that kept creeping up was:

30/03/2016 20:36:10.000 kernel[0]: Sandbox: CommCenter(226) deny(1) file-read-metadata /private/var/folders

There would be maybe 100 of these running at once. All the exact same. In the log this task comes up, for some reason the log flicks out of chronological order after a short time.

Another task that has multiple entries in the log is:

30/03/2016 20:52:08.855 com.apple.xpc.launchd[1]: (com.apple.xpc.launchd.domain.user.501) Service "com.apple.xpc.launchd.oneshot.0x10000003.AppleSpell" tried to hijack endpoint "pt (Apple)_OpenStep" from owner: com.apple.xpc.launchd.oneshot.0x10000002.AppleSpell

Are either of these helpful or should I keep searching?

Thanks again,

Monkton

This one also caused beachballing, I isolated this one:

30/03/2016 21:00:43.000 kernel[0]: **** [IOBluetoothHostControllerUSBTransport][InterruptReadHandler] -- Received kIOReturnNotResponding error - retrying: 1
