You will almost certainly have to update all your apps to match the OS, so you should check that there is a version compatible with the latest macOS (Catalina) for each one. Upgrading 'one big jump' from very old software is more difficult than just 'the next version', because the change is so much larger. The problem comes, as you've found out, when you want something new, and it requires a newer OS than yours. 'Not upgrading' has the advantage that you reached a static point where everything works (or at least has fixed, known bugs). Welcome to the world of upgrading! These days, both Operating Systems and applications are regularly updated to keep pace with progress.
Seems like Apple will only let you download the recent one, but I am not sure.Ī great answer can be just a link to some good article or a similar question on this forum. I am not sure where is a good place to download the update, especially if not the last one. I have several of these, about 80GB on my MacBook Pro.
I am not sure the cloud services I am using, like Dropbox, will not work after the update. Or non-Apple programs, like Mathematica 9, or MikTex. I am afraid that after upgrade some apps won't work or will be missing. I heard it is not a good idea to upgrade to the last OS (possible unresolved bugs, incompatible with some of my older programs). Here are some comments revealing my ignorance, to help you Mac experts guide me: Question: Can you give some advice/tips how to best perform this task? This is the 1st time I am doing this since I acquired this laptop and would like to do it myself (we don't have good Apple support here). Otherwise it works perfectly for all my needs (a research mathematician).
The only reason is that some new programs and devices (eg Wacom tablet) are not compatible with Yosemite. I have a MacBook Pro (Retina, early 2015) with OS X 10.10.5 (Yosemite).
