mac running slow suddenly

Question

Dear All,My mid-2012 13" MacBook Pro suddenly became extremely slow yesterday evening. I restarted it several times, installed the latest software updates without any improvement. This morming I did the following:- I removed com.adobe.aaa.updater-1.0.plist from the /Library/LaunchAgents as I saw in the discussion that this could be a problem- I ran EtreCheck (report below)Surprisingly everything seems now back to normal (?). But I&#x27;m concerned something might be wrong. Particularly: should I be worried about the disk errors? Should I run a disk repair in DiskUtility?Many thanks for your help,JulienProblem description:mac book running extremely slow suddenlyEtreCheck version: 2.2 (132)Report generated 4/20/15, 10:21 AMDownload EtreCheck from http://etresoft.com/etrecheckClick the [Click for support] links for help with non-Apple products.Click the [Click for details] links for more information about that line.Hardware Information: ℹ️    MacBook Pro Intel Core i5, Intel Core i7, 13" (Mid 2012)     MacBook Pro - model: MacBookPro9,2    1 2.9 GHz Intel Core i7 CPU: 2-core    8 GB RAM Upgradeable        BANK 0/DIMM0            4 GB DDR3 1600 MHz ok        BANK 1/DIMM0            4 GB DDR3 1600 MHz ok    Bluetooth: Good - Handoff/Airdrop2 supported    Wireless:  en1: 802.11 a/b/g/n    Battery: Health &#x3D; Normal - Cycle count &#x3D; 344 - SN &#x3D; 9G309005SD3MBVideo Information: ℹ️    Intel HD Graphics 4000        Color LCD 1280 x 800System Software: ℹ️    OS X 10.10.3 (14D131) - Time since boot: 0:43:39Disk Information: ℹ️    APPLE HDD ST750LM022 disk0 : (750.16 GB)        EFI (disk0s1) &lt;not mounted&gt; : 210 MB         Recovery HD (disk0s3) &lt;not mounted&gt;  [Recovery]: 650 MB         Macintosh HD (disk1) / : 748.93 GB (305.69 GB free) - 2 errors            Encrypted AES-XTS Unlocked            Core Storage: disk0s2 749.30 GB Online    HL-DT-ST DVDRW  GS31N  USB Information: ℹ️    Apple Inc.

It won&#x27;t do any harm to do a disk verify and repair. Don&#x27;t use the computer&#x27;s Disk Utility but the one in Recovery mode.Start up by holding down the Command and R keys together and choose Disk Utility. Then Verify and repair your startup disk if necessary and do Repair Permissions.Also, your report shows Spotify web helper linked with crashes. Maybe you should remove that.

Thank you Cunnla. I will do that.J.

Another thing to note is that you have quite a few user login items. One or more of these may contribute to the slow startup. I would get rid of all of them and instead, start them up manually when you need them. You can do this in System Prefs &gt; Users &amp; Groups &gt; Login Items.

The startup drive is failing, or there is some other internal hardware fault. If you don&#x27;t already have a complete, up-to-date backup, do not try to repair the volume. Repairing it is a waste of time in any case.Back up all data on the drive immediately if you don&#x27;t already have a current backup. There are ways to back up a computer that isn&#x27;t fully functional—ask if you need guidance.Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.Keeping your confidential data secure during hardware repairApple also recommends that you deauthorize a device in the iTunes Store before having it serviced.*An SSD doesn&#x27;t need to be zeroed.
