SSD upgrade Macbook Air 2017 iOS catalina 10.15
For the longest time I haven't been able to update my OS b/c of not enough hard drive space. I have a whimpy 121 GB drive. Can I do the following to get more storage and upgrade my iOS?
- make a time machine back up
- install a new SSD drive (1TB? 2 TB? more?)
- restore my time machine back up
- then upgrade my iOS
Are there other roadblocks/issues I will encounter with this idea?
Thanks in advance for any advice/thoughts.
