My mbp is around 4 years old and getting sluggish. I am researching doing a clean install of Yosemite (i.e., backing up all data and formatting the hard drive and the reinstalling Yosemite). There is a lot of info out there on how to do this. My question is this: some guidance has me creating a "bootable installer drive". Other guidance doesn't mention that. Is creating the bootable drive really necessary? Thanks for your help.
Got a tip for us?

The bootable installer drive just means you don't HAVE to have an internet connection to complete the install. Without the drive, you need to have a stable internet connection to allow Internet Recovery to do the job. Using the drive, the install will go faster but no matter what you'll be waiting for the OS to download, using the drive just shifts that wait to before you wipe your system.
If you do internet recovery then you will only be able to install the OS that your computer came with when new.
Not a big deal since you can upgrade to Yosemite afterwards but just wanted to let you know.
Easiest way is to just make a bootable USB.

Thanks for the heads up on that. I am poking around to see what is involved in making the bbotable drive. I took a look at Diskmaker X. When I tried that, it said I was missing the OSX installer app. I guess that is automatically deleted when an upgrade is installed. I thought I could download it from the apple App store. Not finding it but will keep trying.
Thanks again.

Thanks. I found it, I think. Downloaded it and it went to the applications folder. Now when I run Diskmaker X, I select Yosemite and it comes back to tell me no installer app could be found. I browse and select the 152K file I downloaded (OSX Yosemite) and now diskmaker says that file can't be used to create a lion installation file. The download page says it should be compatible with Yosemite. Hmmmm.....
