May 30, 2016 7:14 AM in response to aliciafromharrisonby Lanny,.... when my computer can only upgrade to Mountain Lion?
Any Mac that can run Mountain Lion can run El Capitan, as the requirements are identical.
Too little information: You should identify the model of your iPhone and explain exactly your issues. There is no way anyone would be able to help otherwise.

Mac OS XI have 10.8.5 on my iMac and was suggested by apple not to upgrade to el capitan for it would make my computer sluggish so I am concerned about doing updates on the phone. How do I stop the phone from reminding me to update daily ?

Currently, you do not have to upgrade the OS X on your Mac if you do not want to.

I don't know who at Apple told you that, but OS X Mavericks (10.9) and beyond have significant under the hood improvements that should result in enhanced performance over Mountai Lion. IMHO.
Memory management alone is worth the price, and El Capitan is free. Since you should always have a full backup of your system before upgrading, there should be no risk involved in trying it out first.
If you don't have a backup, what are you going to do when your hard drive fails?

Jun 2, 2016 8:21 AM in response to aliciafromharrisonby Eric Root,If you upgrade, you will want 4 GB of RAM minimum, and more is better. The 2 places I’ve seen recommended most to buy reliable RAM are below. I have purchased RAM several times from Other World Computing and have always been very satisfied with the product and service. They have on-line instructions on how to replace the RAM. OWC has also tested RAM above what Apple states is the maximum. I now have 6GB installed on a early 2008 iMac supposedly limited to 4 GB and noticed an improvement.
One option is to create a new partition (~30- 50 GB), install the new OS, and ‘test drive’ it. If you like/don’t like it it, you can then remove the partition. Do a backup before you do anything. By doing this, if you don’t like it you won’t have to go though the revert process.
Check to make sure your applications are compatible.
Applications Compatibility (2)
El Capitan 10.11 Compatibility information
Open Disk Utility, select your hard drive (step 1), then the Partition tab (step 2), and select the partition. Using the /// at the bottom move it up (step 3) until the size box decrease by about 50 GB. Select the newly created space and hit the + button (step 4). Name it something and select Mac OS Extended (Journaled) as the format (step 5). Then hit the Apply button(step 6). Download the installer from the App Store and when it starts, point it at the new partition. You might want to make a copy of the installer outside the Applications folder to avoid having to re-download it in the future. Once installed, go to System Preferences/Startup Disk, select the new partition and reboot. Test away.
