MacBook Maintenance/Improvement - Running Slow

Post by LuigiLikesPizza » Mon Oct 30, 2017 10:48 am

Over the past few days, my Mac has become extremely slow and wonky, requiring me to Force Quit applications frequently.

I run the Disk Utility/First Aid - and it helps a little, for a short amount of time - not sure what else to do and my understanding is that there is no software to be downloaded for viruses, malware, etc....since this is a Mac.

Any advice is appreciated.

Not true, and since this occurred relatively quickly, there may very well be something wrong. Have you installed or updated any software? What exactly is slow?

Try using Activity Monitor to see if you can identify what is overloading the available resources?

I recently called Apple and they helped me install malwarebytes which is now protecting my Macair laptop. Did you delete your browsing history and restart your computer? Those are the only maneuvers I know.

When my old Mac does this - I open a cmd tool/console (unix command line) - and simply type 'top'

Then look at the top list of high CPU processes and google each of them - you might find something running or enabled that is causing your issue.

I'd call Apple customer care. They are usually very good, and help justify the price premium. This has been my experience anyway.

If it is a few years old, has a hard disk drive, and you plan on keeping it for a while, I would highly recommend upgrading to a solid state drive. The prices continue to decrease, making it well worth it for the increase in speed you will notice. I made the swap a few months ago in my mid 2012 MBP and it feels like a different computer. The swap is super easy to do, just look it up on youtube.

I tried this and got this result and don't know how to interpret it.... is there a next step I should do?

"Processes: 238 total, 2 running, 5 stuck, 231 sleeping, 1553 threads 08:04:17

p.s.: I looked up how to do it and these were the steps- click on launchpad (looks like a rocket), click on Other folder, click on terminal, type in top.

The top part you have is the system summary - what you want is the bottom part and to watch it for a few seconds - perhaps minute. It should look like:

PID COMMAND %CPU TIME #TH #WQ #PORT MEM PURG CMPR PGRP PPID
2106 top 2.9 00:00.59 1/1 0 19 1744K 0B 0B 2106 2103
2103 bash 0.0 00:00.01 1 0 15 556K 0B 0B 2103 2102
2102 login 0.0 00:00.06 2 0 27 984K 0B 0B 2102 2100
2100 Terminal 0.4 00:01.00 8 2 188 9480K 8192B 0B 2100 1
2099 com.apple.In 0.0 00:00.04 2 0 40 1556K 0B 0B 2099 1
2097 AppleSpell 0.0 00:00.03 2 0 43 1160K 0B 0B 2097 1
2096 bootpd 0.0 00:00.01 2 0 19 772K 0B 0B 2096 1
2094 CVMCompiler 0.0 00:00.10 2 1 28 5680K 8192B 0B 2094 1
2092 com.apple.We 0.0 00:01.89 8 3 96 7268K 0B 0B 2092 1
2091 com.apple.We 0.0 00:02.71 8 1 180 46M 100K 0B 2091 1
2089 syncdefaults 0.0 00:00.31 2 0 57 3836K 0B 0B 2089 1
2088 syncdefaults 0.0 00:00.37 2 0 51 3544K 0B 0B 2088 1
2086 Safari 0.0 00:03.16 9 1 275- 40M- 120K 0B 2086 1


The %CPU is how much CPU the program is consuming at that point in time - so top is at the top in this example. Also look at the TIME - that is how much time it has been on CPU - more time = more heavy a process. Look for programs that bounce to the top as you are doing things - that might trigger a flag for me - is this spying on me/malware? Then search on their name.

Ex - I might ask - what the heck is that CVMCompiler - I search on it and find:

https://discussions.apple.com/thread/34 ... 0&tstart=0

That it is part of the system from my quick read - so it is OK - onto the next one.

Some times you will score and find an article that discusses it and how to turn it off or tune it to run less.

If you need more details - control c or open a second terminal and use ps -ef | grep <PID>

ex
ps -ef | grep 2116
502 2116 1 0 8:16AM ?? 0:05.97 /System/Library/StagedFrameworks/Safari/WebKit.framework/Versions/A/XPCServices/com.apple.WebKit.WebContent.xpc/Contents/MacOS/com.apple.WebKit.WebContent
502 2118 2103 0 8:20AM ttys000 0:00.00 grep 2116

That will give you more details about the process.

Good luck.

Based on the top, it looks like your Mac has 4 gigs of RAM. CPU was mostly idle (good, but doesn’t solve your problem). I recommend 8 gigs of RAM. But since that requires money to fix let’s try everything else first.

1) Reboot
2) Run with as few applications as possible. Not using that excel spreadsheet? Exit that app.
3) Only have one user logged into the Mac at a time (since it’s a laptop this is probably already true).

Did you do a software upgrade recently?

I recommend http://crucial.com for Mac memory upgrade information. Some models are upgradeable. Some are not.

EDIT: Make a backup of your critical data as soon as possible. Memory upgrades have some risk. Sometimes a slow hard drive indicates a possible upcoming failure. And everyone should have a backup anyway.

Good catch - I agree - go to 8GB ram - that will make a difference and is easy and cheap to do. I have a very old macbook - aluminim frame - probably 2009 or so - that I just upgraded to 8GB from 4 - easy to do and allowed me to run the latest Mac OS. Its not the fastest but man that macbook will just not die.

My mid-2012 MacBook Pro with 4 GB of RAM began slowing down a couple of years ago. I replaced the 500 GB hard drive with a Crucial 750 GB solid state drive (SSD), and it's been much faster ever since.

I gotta do that too - that will give even more life to my old Mac.

Hello. I am a big believer in doing the cheapest, easiest steps first. Why spend money if you don't have to, right? I would start by checking

1. available memory.
Click the Apple logo in upper left hand corner
About this Mac
Storage
You want to have at least 10-20% free, but the more free space the better. If it's close to full, backup to external hard drive and free up memory or it's time for a bigger HD.

2. Delete unnecessary items off desktop or put them in a different folder

3. Empty trash

4. Clear Cache
Finder
Go
Hover over "Computer"
Hold option
Click library
"Caches" folder
**Make sure you are in the Caches Folder**
Single click "CFbundle Identifier"
Hold Command key + Click A button
Drag and drop into trashcan

5. Safari
Open safari
Click Safari
Clear History

6. Check log in items
Apple Logo
System Preferences
Users and Groups
Select your user having the issues
Select any items you do not want to load automatically
Click minus (-) sign to remove them from the list



If you are still having problems now is the time to think about spending some :moneybag :shock:
Again, I would do cheapest to most expensive

1. Upgrade your ram. ~$100
I would at least double what you have now. Apple low balls the amount you should install, while 3rd party have verified larger RAM is safe.
https://support.apple.com/en-us/HT201165
https://everymac.com/actual-maximum-mac ... acity.html
(Apple also has this info on their site)

2. Replace HD with SSD ~$150 for 500gb, $300 1tb



Hope some of this helps. Typing this on my completely stock mid 2012 MacBook I'm starting to think I will need to upgrade the RAM soon as well.
Good luck!

SSD with 4GB memory will be faster than 8GB memory with a hard drive.

I've upgraded a couple of 2012 used MacBook Pro models to a 256GB SSD but left them with the stock, 4GB memory.

When you run First Aid in the Disk Utility, what does it say?

Another possible problem you may have is a failing hard drive. In my case the solution was to replace my hard drive with an SSD, killing two birds with one stone.
