Please let me know if that didn't work, so we can continue troubleshooting.
Well, I tried what you suggested and I've turned on firefox again. Not sure how to check if it's up to its normal speed though. It still seems sluggish, but I want to be objective about this.
I don't hear nearly as many "bubbles" as I did earlier. I think it's faster now. Again, is there a way to check it? Any place to look on the computer to find a quantifiable improvement?
I have an iMac 10.8.4, and that version is not covered by Onyx. Otherwise, sounds like a good thing. I am pretty IT illiterate. You don't suppose I made a mistake so far as Onyx goes, do you?
I hate to be so high maintenance, but I downloaded the Onyx software and then when I tried to open it I get this message: "Onyx" can't be opened because it is from an unidentified developer. Your security preferences allow installation of only apps from the Mac App Store and identified developers." I don't know how to rectify that. When I open "security and privacy" the message says that my firewall is inert. What else is there that I can adjust that would allow use of Onyx?
I got hung up again. A message pops up that says, "OnyX" requires that you type an administrator name and password." The name which appears in the blank is mine, peggy, and the password XXXXX is blank. My normal "password" to alter my computer settings is simply a click of the "return" key. That doesn't work in this instance. Any clues?
I finally ran it, and all is well. Thank you very much, Ashik!
Ashik, I already rated your service as excellent. Did you not see the rating??
OK. It's good. Thanks!!
