Macbook Pro 2009 with 500 GB HDD and 4G RAM running Yosemite. Been slow last couple of years or so. Got 30 GB left out of 500 GB hard drive. Opening an app can take minutes and dozens of icon bounces. I shutdown and restart quite often, and run CleanMyMac once a month or so. Those actions only temporarily help before the beachball comes back again. Would replacing my HDD with a new one speed laptop up like new? I though of replacing with SSD but ilthose are still quite expensive. Thank you
Apps I run almost everyday: Safari Word Excel Mail Transmission
Apps I sometimes run (maybe once a month or less): Photoshop Lightroom
Screenshot of current Activity Monitor. Took a dozen or so seconds just to wake up from sleep. Sometimes even takes half a minute to a minute. Just now Safari took 50 bounces to open.
