Q: iMac mid 2011 speed and Mac OS security
To all: Thanks in advance for reading this and pointing me in the right direction
I have an iMac 27 inch mid 2011 with 16 GB ram, using about half of the hard capacity of 1TB and have a 200GB iCloud account with about 180 GB of images. I just recently upgraded to Mac OS Sierra. I have no files stored on the desktop. I have some concerns about how the machine has slowed since I purchased it new in the late summer of 2011. I started using the "Dr Cleaner" app awhile back but using it did not speed up the machine. I have a 100MB internet connection. Btw, I do not run any extensions and use the Safari browser.
(1) What procedure should I use to clean up any unnecessary processes or apps that serve me no purpose?
(2) How can I check that my iMac is not infected with Malware, Virii, or Adware? if it is what countermeasures may I take?
(3) It is slowing down due to the increased number of the OS processes running on an older processor? How may I confirm or deny this hypothesis?
Once again thanks again for your counsel,
