[Closed] Macbook osx Help please

Is it not in App Store in 10.9?

App Store - free purchase of 10.10 or whatever you need and off you go.

Does this help? https://support.apple.com/en-gb/HT206886

Edit - from the support document, seems you can go straight in and install 10.11. Apple support site. 10.10 is available on this document: https://support.apple.com/en-gb/HT210717

Thanks euain

So it appears I might not need 10.10 - and can go straight to 10.11 from 10.9?

That would save a lot of faffing about.

Looked in the app store on my machine and only catalina is showing as available -

Apple Store shows the latest version available for your machine. If Catalina is available just install that.

App Store isn't quite that clever. I've had it perform a download just for the machine to then say it can't run it. That machine will not do Catalina.

Support notes seem pretty useful, I'd go with whichever one seems to suit best. Straight to 10.11 might be least faffing.

Yes - even though catalina is available - the notes dont list my 2009 macbook as compatible.

I am actually downloading 10.10 at the moment - but may just try and go straight to 10.11

Will be nice to get it working properly again.

I had a 2009 MacBook until about 2 years ago when the battery decided to swell up and break the intervals. Up until that point I had kept it updated with the latest OS X of the time, can’t remember which one but a god couple or few past Mavericks. It had no issues running with maxed out ram and a 1TB hybrid drive with 8gb SSD portion. If you can update then it might keep you trucking a bit longer.

I believe if you do a recovery boot (hold ⌘R when turning on) you'll drop into the recovery OS which has a reinstall button. Remember to make sure you've backed up everything with Time Machine, once you've done a reinstall you can just restore the user data from the backups to ensure that you're not infecting your fresh install with bad files from the previous install.

It's been a while since I did one of these but this link should upgrade you to the latest version of 10.11. There may be a couple of security updates to download after this once you've finished.

Think this is what you are looking for..  I think a 2009 Macbook Pro can only go as far as ElCapitan although you might be able to go to Sierra depending on your exact model..

All the info you need should be here...

And just incase..

How to upgrade to macOS Sierra

All the links you should need are on the page, with download links to the install image files.

#EDIT: Given the issues you are having I'd recommend backing up and doing a clean install. Not usually required for MacOS but under the circumstances it would probably help.

I would follow H1ghland3r's advice. You don't need to install 10.10. A wipe and clean install is the way to go. I've upgraded a few Macbooks and Minis from 10.9 to 10.11, though they usually get a bit tardy. If you can justify it, fitting an SSD drive and 8GB of RAM has hugely improved the 3 Macbook Pro models in our office.

Once you're up to 10.11.6 then I'd use the App Store to add any further updates like Safari, Sec Update (2018-004 IIRC). I have tried to install Safari and Sec Update on 2 separate machines from a previously used .pkg files - exactly the same no. of bytes, creation date etc - but it wasn't happy so I let the App Store update them.

Backup your data, keychains, preferences etc then download new versions of Skype, Dropbox and other software.
