Imac Starting To Slow And Increase Hard Drive Paging

Mar 23, 2011
Reaction score

I have been noticing that my computers seems to be getting slower, and also I am noticing much more hard drive paging, to the point where it is a concern. I do not do any graphics or high intensity CPU usage on this computer. I have run the disk utility from the Mac, and no issues found. Is this a sign that the hard drive might be failing? Or do I just reinstall operating from scratch?

If hard drive failing, on this computer, can I put one of the new solid state drives?

Thanks JR

If you haven't found anything yet,

4gigs of ram is really low for todays apps and OS's. Just adding another 4gigs should help out on slowing down the Page Outs. The extra ram also helps out when using multiple apps at the same time or having a lot of open windows in the browser for example. From what I understand the OS is resorting to using the HD as a "Ram disk" because it ran out of dedicated ram. The rainbow spinning curser is another sign of low ram.

There are a fair amount of things that happen when a HD starts to die. It seems like no two HD will give the same clues. Usually you will start to get corrupted files or it will take a long time to boot up or just die and not be useable at all. I believe HD's have a 3 to 5 year average life span. I've had some, from every brand, die in 6 months and yet my SCSI drive in my old Sawtooth G4 tower was still going strong after 10 yrs before I retired it. If your drive is 4 or 5 years old I would probably think about retiring it to an external HD housing and using it as a temporary drive for odds and ends.

I believe you can use an SSD but for the most bang for your buck the OS should really be the only one on the SSD drive and keep a standard HD for your applications and storage. From what I understand the SSD is not happy with a lot of writes/erases, it shortens the life span.
You may need a "caddie" in order to use the SSD in your HD spot as the SSD is much smaller then a standard HD. OWC ( and others have a lot of information and other goodies that you can use.

If you upgraded 10.10 over 10.9 it may have left some old files that 10.10 may not like? It's usually suggested to fresh install (erase/install) the new OS instead of upgrading over the old one, then use your backups to install the files you need. It's not as big a problem as it used to be but it can make it buggy for some. Another thing that helps when reinstalling the OS is to use the "Combo" updater instead of updating it one by one.

Hope this helps,,,,

OSX likes 20% of the hard drive to be free.

If you have less than this the amount of paging and rewriting to disk increases to the point your Mac can grind to a crawl.

Simply back up as many non-essential files to an external WD Passport hard drive, or replace the internal HDD with a much larger one. Swapping them in all but the very latest Macs is a simple procedure, you just need some small screwdrivers for the tiny screws.

A SSD drive is just as easy and doable, just the capacity will be much smaller for your money and if your HDD is too small now, an SSD will be even smaller so still be paging, just paging faster, not a solution.

You can determine the S.M.A.R.T. status of your selected internal hard drive at the foot of Disk Utility. This is no guarantee of predicted failure however, it just may give some warning.

I don't think the increased paging indicates a dying hard drive. That is usually a good indication that more memory is needed.

Apple officially says 2 GB is the minimum amount of memory needed. Many of our members myself included think that number is a bit light. Most of our members suggest 8 GB is needed for good performance.

I don't think this will slow your Mac down, but your /etc/hosts file is listed by etrecheck because it's been modified. Have you done this to simplify access to other computers on your local net? If not, you should investigate what change was made (& was it by malware, for example).

Thank you for all the great info. I think I might try doing a fresh install of the latest Mac Operating System. Is it best to format the drive then a install, or if installing from scratch, does the software first start with that procedure?

Thanks Jr

gaspower your iMac can run up to 32GB of memory. It is being throttled. Just increase to 8GB before you consider a clean install.

Just a quick note. I reinstalled from scratch Yosemite and it works great. I think from all the years of updates and upgrades it just needed a fresh install.

Thanks JR
