Suggested to a friend that he replace the HDD in his 13-in MacBook Pro, 2009 vintage with an SSD. He did that a week ago, boot-up time dropped from 3 minutes to 1-½.
On Wedsesday he said it must have been doing some sort of indexing as it was now booting up in 50 seconds. I asked him to bring it to the Men’s Shed the next day.
So yesterday (Thursday) I ran DiskWarrior on it. I’ve just received an email from him saying he’s getting DiskWarrior himself as it now boots in just 25 seconds.
