Downloading the latest Mac OS this next week is the easy part. Unless you start the download when another 2 million people are doing the same thing, Apple makes the upgrade process very painless. And of course, it is free, too! There are some steps you should consider as you prepare for El Capitan to make it a smooth process.
BACK UP!
Yes, I am shouting! Back up your data all the time but especially whenever you are updating your operating system. We have talked endlessly about how fabulous Time Machine is as a tool to back up your data. DO IT NOW. Upgrading to El Capitan is a great excuse to make a fresh back up of your priceless data.
Do you know who you are?
Do you know your Apple ID and the password? You are going to need that to upgrade. It will be asked for when you start the download and you will also be asked for it during the El Capitan and iCould setup. If you wrote it down on that little scrap of paper that is somewhere in your wallet, now would be a good time to find it.
How Old is Your Mac?
Sorry, that old SE 30 will not support El Capitan so you should make sure that you know if your Mac will support the new operating system. Here’s a list of the supported machines:
iMac (mid-2007 or newer)
MacBook (late 2008 Aluminum, or early 2009 or newer)
MacBook Air (late 2008 or newer)
MacBook Pro (mid- to late 2007 or newer)
Mac Mini (early 2009 or newer)
Mac Pro (early 2008 or newer)
If you do not know your model you can go under the Apple menu and select About This Mac and if you are running Yosemite you will see something like this screen shot that will show you the vintage of your Mac.
RAM and Storage
The two mostly commonly confused terms in technology. Well, you need enough of both memory and storage. In the case of memory, Apple recommends a minimum of 2GB, however; Small Dog Electronics would set that minimum at 4GB. I think you will find your experience with El Capitan to suffer with only 2GB. If your Mac’s memory can be upgraded, now might be a good time!
Storage is also important. We always recommend that you have at least 10-15% of your hard drive or SSD drive free just for cases like this. The installation of a new operating system creates a lot of temporary files that need space to live before they are ultimately deleted by the installation. Apple says that El Capitan takes about 6GB and that you should have 8GB free. That is cutting it pretty close. I would recommend that you have a minimum of 10GB free and pay close attention to the 10-15% free space. Now would be an excellent time to purge some files and old stuff that you really don’t need – like that downloaded copy of the Sopranos last season.
Are you up-to-date?
Is there a number in the icon of the App store? Have you done all your updates for the operating system and apps? Developers have been optimizing their Apps for El Capitan for several months so doing all those updates before you upgrade to El Capitan may make things go easier for you, too!
