MacBook Pro won't open the App Store when I try to upgrade OS
I have a 2010 MacBook Pro running OS X Mavericks 10.9.0. Why won’t it open the App Store when I try to upgrade to 10.9.1?

Don't know why the App Store is not opening but if you want to update your Mavericks OS you can download from the Apple Support Downloads site.
The last version of Mavericks is version 10.9.5, unless there is a reason you only want to update to 10.9.1.
Click on the link below to download the 10.9.5 Combo, this updates any previous version of Mavericks to 10.9.5.
Once downloaded double-click to install.

If you do actually want to UPGRADE your mac to a newer OS then that will depend on the model and year of your mac.
Please use Safari to access the following links do not use Firefox
read Section 1 in each case.
How to upgrade to macOS Mojave - Apple Support
How to upgrade to macOS High Sierra - Apple Support
How to upgrade to OS X El Capitan - Apple Support
Before upgrading make a full back up of your Mac.
Check that third party apps you use have updates available for the new OS.
Check that your printers/ scanners etc have updated drivers and software available for the new OS.
Connect your mac to your router via cable rather than rely on WiFi.
Do not use your mac while it is downloading
and do not use any other devices that share the same internet connection.
If the App Store says ‘Open’ then it is detecting a previous download of the install app
go to the Applications folder locate Install macOS ******.app.
Move it to the Trash, empty the Trash.
Restart, click on the link again, the App Store should say ‘Get' or 'Download'.
If you are considering upgrading to Catalina be warned that it does not support 32bit apps.
Your Mac is probably running 32bit apps and these will need to be updated to 64bit apps,
some updates may be free, some may be paid. Use this app to discover which apps you have
are 32bit, https://www.stclairsoft.com/Go64/. Once the list has been created you can then
contact the developers of the apps to see if they provide 64bit updates.
