Clearing cache and cookies in Google Chrome on a MacBook Pro

Apple menu (the Apple logo in the upper left) -> About This Mac will tell you what Mac OS version you are using and what Mac model/year you are using. This information will be helpful for us to give you further help.

David Pogue has written a "missing manual" for most every Mac OS. There is also a very good visual start guide.

Chrome caches are cleared using this link in the address field (use the Edit menu to find Copy and Paste)

chrome://settings/?search=cache

there is also on the far right three dots lined up vertically which has a pull down menu that includes Settings for all Chrome Settings.

Keep in mind, if you got a computer from someone else, if they left you software on it, wipe it clean and start fresh. Once we know your current Mac OS, and model year/Mac model, we can tell you how to do this. The fact you have Chrome makes us wonder did you download it, or did it come with the computer? If it came with the computer, you still have software left from the prior owner.
