Should I upgrade from OS X 10.9.5 (13F1911) on my iMac 21.5 inch, late 2013?

The Recovery Partition is found by holding down the Command and R keys on startup.

from there you can launch Disk Utility.

once you have verified the drive is okay then restart the computer normally and back it up using Time Machine and then you are ready to upgrade to High Sierra which is the most current version of Mac OS. Update from the Mac App Store.

sounds like you are well on your way to discovering the issues with upgrading the OS as it relates to the hardware drivers of all other devices you use, i.e printer, camera, etc... you may find that upgrading the OS requires you to upgrade other devices you have as well to restore the functionality you had before the upgrade.

One reason to keep your machine current is to get the Security updates. When a vulnerability is discovered, it will be exploited, the older OS versions may never get updates to the latest security threats out there, while the Mac is not a common target it is not totally immune to spreading a virus to other vulnerable machines. Apple may still be releasing security updates to 10.13, 10.12, and 10.11, but I don't think you will get updates to 10.10 or 10.9 anymore, so if you are not connected to the internet then who cares?

Another idea, is to get an entirely new hard drive, backup your entire internal drive, using Carbon Copy Cloner, or Disc Utility, Super Duper, Deja Vu. Now, you can have the old OS available to boot from the external drive, and as a bootable backup in the event the upgrade does not go smoothly. Upgrade the internal drive OS after you have made the backup clone on the external drive. You can still boot from the old OS to print things with your old printer. Boot from the new OS to try things out and find out what else might work or not work, and get that new printer when you are ready, unless you can find new drivers. If you have a backup, then you can use both 10.9 and 10.13, just decide at boot time by pressing the "option" key to pick which one.

Hello Linda.

Nice to see you were so pleased with Allen's reply. Are you sure you clicked 'reply' on his post to you ... and not on your own post reply (which would not connect).

Try again and click on Allen's last reply to you. Then refer him to today's post.

Yes, I see the problem now. I have direct contact with mnay members but not Allen. If i see him featured I will use the thread that he is in to draw his attention to you.

As far as High Sierra is concerned I would personally encourage you to stay with it. Not only is it the current System but in my view is a step up from Sierra.

I have a personal policy of not updating to a new operating system until it reaches the second update. High Sierra is now on its third and I followed my policy and updated in January. I have no regrets. Thank you for the star.

Good morning Linda,

Call Cannon and ask them. They have facilities in most major countries and you should be able to talk one to one on the phone. Their technical department will have been asked this many times.

Good morning.

We are all volunteers here and our home obligations means we are not always available ... or there is no-one looking in who can answer your question.

Don't mention to them that you are prepared to buy another printer until you have exhausted their suggested remedies. They may see it as a discouragement to solving the problem!

Let us know the result.
