Recently I've been noticing that my iMac constantly freezes and the rainbow spinning wheel always appears. I don't know what's causing this problems so I hope someone could help me
Thanks un advance
iMac, OS X Yosemite (10.10.5)
Check out the following article links:
Troubleshoot the spinning beach ball/freezing & crashing
Troubleshoot the spinning beach ball
When you see a beachball cursor or the slowness is especially bad, note the exact time: hour, minute, second.
These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
The title of the Console window should be All Messages. If it isn't, select
SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar at the top of the screen.
Each message in the log begins with the date and time when it was entered. Scroll back to the time you noted above.
Select the messages entered from then until the end of the episode, or until they start to repeat, whichever comes first.
Copy the messages to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
The log contains a vast amount of information, almost all of it useless for solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
Some private information, such as your name, may appear in the log. Anonymize before posting.
When you post the log extract, you might see an error message on the web page: "You have included content in your post that is not permitted," or "The message contains invalid characters." That's a bug in the forum software. Please post the text on Pastebin, then post a link here to the page you created.
Thanks for answering. It's almost impossible to do just a simple copy and paste of the log from the Consolé, but as I was able to see, everytime the iMac freezes the error kernel: disk0s2: I/O appears. Does it has something to do with a hard drive failure? Anything I can do?
Try running this program and then copy and paste the output in a reply. The program was created by Etresoft, a frequent contributor. Please use copy and paste as screen shots can be hard to read.
I copy to you the report log of Etrecheck.

The startup drive is failing, or there is some other internal hardware fault.
Back up all data on the drive immediately if you don't already have a current backup. There are ways to back up a computer that isn't fully functional—ask if you need guidance.
Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
Keeping your confidential data secure during hardware repair
Apple also recommends that you deauthorize a device in the iTunes Store before having it serviced.
*An SSD doesn't need to be zeroed.
Thanks for your reply. Could you tell me how to do a back up if the computer is not fully functional?
Thank you.
Try using Disk Utility/Restore to copy the backup to a new location. Please note that this will reformat the destination partition.
Thank you, I was able to do a back up using Time Machine
Here is the link to my pastebin. Thank you for any help you can provide.
