problem updating to OS X 10.10.4

Hello there, jyencapacite.

It sounds like you're having issues updating Mac OS X Yosemite to the latest version of 10.10.4. The following link takes you to file you can download and install:

OS X Yosemite 10.10.4 Combo Update

Thanks for reaching out to Apple Support Communities.

Cheers.

Hello again, jyencapacite.

Thanks for your question to clarify about the update. Yes, you are correct. The file, once downloaded, just needs to be launched (it may launch automatically depending on your browser settings). This will initiate an installer which should walk you through the process, just like when you update through the App Store.

Kind Regards.
