fixed : spinning beachball on extremely slow MacBook Pro from 2012

Question :

I have a MacBook Pro from 2012 (maybe 2011) and it has gotten slower and slower each year, and now it’s even so slow that I constantly shows a spinning rainbow-ball and apps keep bouncing in the Dock : everything from opening apps to opening files takes forever… the response time to what I type on the keyboard is extremely slow… even though I am sure I haven’t even used 50% of my hard disk space…

What can I do to resolve this ?

 

Answer :

If you have a MacBook Pro ‘late 2011’ or ‘mid 2012’, and you have never upgraded the RAM, your MacBook may only have 4GB of RAM. Compared to current standards, that’s very little… especially if you are running macOS 10.13 High_Sierra or newer (macOS 10.14 Mojave will not run on the ‘late 2011’ model, only on the ‘mid 2012’ model).

There are various possible causes for your Mac running slow, to name a few :

  1. your hard drive is too full (not in your case as you stated, but still worth mentioning)
  2. you have too many processes running at once, so you’re short on RAM
  3. over time some things have gotten messed up on your Mac

So, start tackling these potential problems one-by-one :

  1. check your free hard drive space and free it up if needed :
    • go to the Apple-icon (top-left in the main menu bar)
    • from the pulldown-menu choose About This Mac
    • in the window that opens, click on the Storage tab
    • an info bar shows up :
      • if you have more than 25% of space available, you’re okay
      • if you have less than 10% of space available, you should free up space as soon as possible
    • to free up space on your hard disk, you can :
      • move files you do not use regularly to an external drive
      • delete apps you never use (apps from the Mac App Store you can delete, since you can re-download them if you need them in the near future ; other apps you should backup to an external drive if you want to be sure you will be able to re-install them in the future)
      • click on the Manage-button in the window you were in (About this Mac -> Storage) and follow the suggestions to free up space on your internal hard disk
  2. check your available RAM and shut down background processes :
    • go to the Apple-icon (top-left in the main menu-bar)
    • from the pulldown-menu choose About This Mac
    • in the window that opens, click on the Memory tab
    • if you only have 4GB of RAM, it would be a good idea to upgrade your RAM (but if you do not use your MacBook intensively or intent to buy a new one within about a year, it’s not a very cost efficient solution, so you can choose not to)
    • if you want to upgrade your RAM, you could ask your local Apple-dealer to do so for you, or you could do it yourself if you are a little tech savvy and have the right tools :
      • for a Late 2011 MacBook Pro you need PC-10600 (1333 MHz) DDR3 SO-DIMM, either 2x4GB or 2x8GB
      • for a Mid 2012 MacBook Pro you need PC3-12800 (1600MHz) DDR3 SO-DIMM, either 2x4GB or 2x8GB
    • whether you upgrade your RAM or not, you should also open the Activity Monitor app (that is in the Utilities folder within the Applications folder)
    • in the window that opens, you can see which apps and background processes take up the available RAM capacity
    • if you encounter any app in top-10 of the list that is either running slow or that you don’t need, you can Force Quit the app by selecting it from the list and then clicking on the 8-sided-X-marked-button top-left ( NOTE : only do this with apps you know, do not do this to processes from the list that you do not recognize, or of which you do not exactly know of what they do… it’s far safer to keep one process too much running than one process too little ! )
    • then, go to the Apple-icon (top-left in the main menu-bar)
    • from the pulldown-menu choose System Preferences
    • in the window that opens, click on Users&Groups
    • in the window that opens, click on the current user in the list on the left
    • then click the Login Items tab
    • there, make sure to only leave iTunesHelper there, so delete all other background-apps listed by selecting them from the list and clicking on the Minus-button bottom-middle ( NOTE : background-apps that are known to slow down your Mac extremely if you have little RAM are SpotifyHelper and Dropbox (DropboxHelper), so make sure you delete both of them if you are not planning on using Spotify or Dropbox regularly )
    • then restart your MacBook Pro ( go to the Apple-icon top-left and select Restart from the pulldown-menu )
    • after the restart, check to see if the background-app you had just deleted are really gone from the Login Items list, if they haven’t, delete them again, restart & check again
  3. if your Mac is still slow after doing all of the above, reset the PRAM/NVRAM/SMC by doing the following :
    • disconnect all cables from your MacBook Pro ( also disconnect from all USB-devices )
    • restart your MacBook Pro ( go to the Apple-icon top-left and select Restart from the pulldown-menu ) to ‘zap the PRAM’ :
    • when the screen goes black, immediately press this key-combo on your keyboard : [P] + [R] + [ALT] + [CMD] and hold all of them until you hear the second startup chime (sound), then release
    • then also ‘reset the SMC (Software Management Controller)’ :
    • make sure your MacBook Pro’s power adapter is disconnected
    • restart your MacBook Pro ( go to the Apple-icon top-left and select Restart from the pulldown-menu )
    • when the screen goes black, immediately press this key-combo on your keyboard : [SHIFT-left] + [ALT-left] + [CMD-left] and press the [POWER]-button at the same time for 10 seconds or more, then release
    • then press the [POWER]-button again to start-up your MacBook Pro

That should do it !

enjoy 😉

fixed : macOS Sierra downloaded but installer won’t run

Question :

Since the latest version of OSX (entitled “macOS Sierra) has been yesterday, I wanted to install it on my Mac. I clicked on “download” in the Mac AppStore and  the download started ; on the dedicated product page I could see the status bar filling up and finally stating “downloaded”… but then, nothing happened…

The download wouldn’t install…

I re-checked if macOS Sierra does support my Mac, it does. So I tried restarting the AppStore-app, I tried logging out my iCloud/AppStore-account & than logging back in, I tried rebooting my Mac, I tried rebooting in SafeMode, I tried FirstAid in the Disk Utility app, I tried clicking 10 times on the “downloaded” button repeatedly, I tried installing the DeBug-menus & cleaning the AppStore cache, I tried deleting the hidden AppStore downloads folder… and I tried various command line solutions found online in the Terminal app… nothing helped… I am still stuck with the button under the macOS Sierra icon saying “downloaded”… and nothing happens…

What can I do ?

 

Answer :

You are probably not (really) going to like this answer, because this will set you back hours & hours, in which you can’t use your Mac ; but it’s the only way known to solve this, and you need to have a recent TimeMachine backup (or alike) for it :

  1. shut down your Mac
  2. disconnect all cables  from your Mac (except your keyboard & mouse if you haven’t got a MacBook)
  3. restart your Mac, and be quick to press the [CMD]+[R] key-combo during startup (your Mac will now start up in Recovery Mode)
  4. in the “OS X Utilities” window that appears, select Restore From TimeMachine Backup and click Continue
  5. in the next “Restore Your System” window, click Continue
  6. now first make sure that your Mac can connect to your TimeMachine-harddisk by plugging in it’s USB-cable, plugging in your Ethernet-network-cable or connect to your WiFi router
  7. then select the hard drive that has your TimeMachine backups on it and click Continue
  8. in the next window, make sure you select the most recent backup that is from before you tried to download macOS Sierra ; only if you’re sure you’ve selected the right backup, proceed and click Continue
  9. now wait (or do something more useful in the mean time) and wait and wait ; this is going to take hours and hours ; putting back a TimeMachine backup this way will go a a speed of about 30BG per hour, so if your hard drive is 500GB it may take you about 15 hours (yes, an entire night and an entire morning…)
  10. finally, once the TimeMachine backup-reinstall is done, your Mac will restart… just let it
  11. then, when logged in, open the Mac AppStore-app and notice that the button under the macOS Sierra now says “download” ; click on it
  12. after the download has completed, you should now see the installer window popup on your screen… proceed from there…

that’s it… it’s simple, but very time-consuming…

enjoy !
