Google Chrome just seemed generally sluggish all the time particularly on my iMac (mid 2011), though also slightly on my Macbook Air (late 2010).
What fixed it for me
- I quit Google Chrome
- I uninstalled Flash from the Mac, I have deleted the program now so I can’t show you but I believe you need to find a program (do a Spotlight search) called Adobe Flash Install Manager (or similar). Run that and there’s an uninstall option there. Just go through all the steps. (If you don’t have this program or can’t find it I can’t help I’m afraid I can only share what worked for me)
- I uninstalled Google Chrome
- I re-installed Google Chrome
- (Bonus point: If you’ve got 1,000,000 Chrome extensions you’re no longer using you might consider removing a few of these too but it was the Flash step that made the big difference)
Why this (apparently) works
Turns out it’s something to do with Flash (surprise eh). Seems like Google Chrome doesn’t like the standard install of Flash on a Mac though and gets upset.
However if you install Chrome – and you DON’T already have Flash installed – it installs a module(?) that runs Flash anyway and for whatever reason everything then plays much nicer together.
Considering I have Chrome open pretty much all the time, doing the above made everything run much smoother for me. I hope it helps a few other people too.
