Upgrading a late 2009 iMac
I need help in updating the operating system on my iMac. I have a late 2009 iMac which is currently running version 10.9.5. I would like to bring it up to date but do not know how I should do that!
Can I just go to the App Store and download MacOS Catalina and install it or do I have to install some or all of the missing updates between Mountain Lion and Mojave before installing Catalina?
Once I install the new operating system I will have to update all the iMac software (Pages. iPhoto, Mail etc.). Can I do that by just downloading and installing the latest software updates for each? Thanks.
