I would do one thing at a time, however, so that if something goes wonky, you know what you last changed.īe patient, this is a lengthy process and at times it looks like nothing is happening. In this case TM will probably be ok because the stick is bootable in an emergency so the TM backup should be all you need to restore your system. Using this approach you can still have a CCC or TM backup on the external drive. Then boot from that USB stick and do the installation from there. When it is done, it will have created an account on the new system with exactly the same name and login as you had originally and all your stuff should be in place as it was before.Īn alternative approach would be to get an 8GB USB memory stick and use DiskmakerX to create a bootable USB stick with the installer on it. Take that opportunity to have it do that and point to the CCC clone for the source. If you do that, when you boot for the first time it will offer to migrate everything for you. If you want to repartition/reformat that will get you a "clean" installation. The default will be to install OVER your Lion installation leaving your data and applications intact. Cancel it at that point because you'll want to save the install file as a backup and the installation process deletes the installation file when it is done.įind the install file (named "Install OS X El Capitan" and in your Applications folder.
(When it is done downloading it will automatically launch. Make the CCC clone of your entire drive to the new external.ĭownload the El Cap installation file. It would be better to make a bootable clone because if something goes south in the upgrade you'll be able to boot from the clone and at least get going again. Thanks very much for any advice or suggestions, I know I am not that computer savvy so don't worry about hurting my feelings, I know I am a dummy about this stuff.Īlso: I am not a heavy duty computer user - have two forums which I browse daily, read the news on various alternate news website, use microsoft excel for mac for financial spreadsheets, and that it is about it. Question: should I make a bootable CCC (didn't know what this was until today) also, as well as the Time Machine backup? Or could I just make a bootable USB drive which I could use to reinstall Lion? I was planning to upgrade to El Capitan by the following steps:ġ) make a Time Machine backup (bought a 1 TB external hard drive today to use for this)Ģ) upgrade memory (I purchased two 4 GB 1333 MHz memory chips today, will give me a total of 12 GB - 2 X 2 GB and 2 X 4GB chips) I have never made a Time Machine backup either, use an external hard drive to back up my personal files that I most don't want to lose. I never got around to upgrading to Yosemite. I have a mid 2011 21.5" iMac with the following specifications:ĥ00 GB SATA Disk with about 300 GB free space.
