So, I have seen a couple of Macs in the past few weeks, of decent spec, running really slowly as well as taking ages to boot (many minutes), I checked all the usual things, such as verify disk, repair permissions, console logs etc. and there were no obvious issues
anyway, I took a look at login items and the only common item for both machines was that the Spotify app was set to run at startup
once this was disabled it was like they were new machines!
if you’re Mac is running slow, and everything seems fine, then try following
Open System Preferences
Then Users & Groups
Then click on your account, and then Login Items
click on Spotify and then click on the minus button at the bottom of the window
Next, click on Finder
then press CMD SHIFT G
paste in the following location
delete the com.spotify.webhelper.plist file
Then reboot the machine
On both the machines I did this on, it was like they were brand new, and both owners were very pleased with the result, hopefully this works for you too
Oh, and the Spotify app still works, a good result all round
To ‘allow applications downloaded from anywhere’ from the command line, enter the following into Terminal
sudo spctl --master-disable
This changes the option located in System Preferences, Security & Privacy, General
This will allow you to install software from sources other than the Mac App Store
Software Updates have now been incorporated into the Mac App Store, which is not something I’m a massive fan of, but I can see why it’s been done.
The good news is that you can still update the System software using the softwareupdate command in Terminal, so nothings been broken by this change.
Gone is the option to choose how regularly your machine checks for updates.
There are now the following options
Automatically check for updates – tick this if you want to be notified when new updates are available.
Download newly available updates in the background – tick this if you have an unlimited broadband/data connection, with some updates being a couple of GB in size now, its not wise to leave this checked with a limited plan, as you could go over without realising.
Install system data files and security updates – does what it says on the tin.
Automatically download apps purchased on other Macs – I leave this unticked as I prefer to choose what takes up my hard drive space on each machine, rather than having all apps install on all machines automatically.
The Mail, Calendar & Contacts preference is the place to set up all of your e-mail and Calendar accounts, it now also has the added Social Media accounts such as Twitter, Facebook, Flickr & Vimeo.
Adding these accounts makes it a lot simpler to upload or share stuff through these sites, system wide.
The Energy Saver preference has a new addition – Power Nap!
This enables your Mac to check for e-mail, calendar and iCloud updates whilst asleep, which is great, as it saves on syncing time when awaking a machine, the downside however is that it uses more power than the conventional sleep mode, so it’s best to use it only when plugged into the mains.
