On September 30th, Apple made its latest version of OS X—El Capitan—available for download from the Mac App Store. In the week that it's been available, the adoption rate numbers have yet to come out, but the overall consensus is that this latest OS is more stable and refined than the previous OS X Yosemite was at its release.
OS X 10.11 is less about whiz-bang new features and more of a maintenance release. Apple chose to fill in the gaps, so to speak, and make the necessary modifications to make this release rock-solid, resolving many of the known issues that affected some Yosemite users, such as Wi-Fi and Bluetooth.
However, there are still a few issues that have come up in El Capitan. While they're not as glaring, per se, they can still be quite annoying! So, let's take a look at some known issues and how to resolve them.
- Prepare your Mac for the OS X 10.11 'El Capitan' upgrade. Apple is scheduled to release the next version of OS X - OS X 10.11 'El Capitan' - later today, which means that you still have time to.
- What is the best antivirus for Mac El Capitan? Discussion in 'Mac Apps and Mac App Store' started by RLM365, Feb 5, 2016.
- I am running under El Capitan, I suspect your kext is not properly signed and under El Capitan the OS won’t run it, suggest you discuss with the programming team. I had other software which used to work and under El Captian failed until vendor supplied a updated.kext file.
- If you absolutely have to have an AntiVirus program running, try Sophos AV for Mac, which is free.That does work with El Capitan.
1. Upgrade installation error messages
AVG AntiVirus for Mac helps keep your Mac free of viruses and running smoothly. Through its intuitive interface, this app lets you manage your security settings and run scans at any time to ensure complete protection.
Symptoms: After downloading the OS X El Capitan Installer from the Mac App Store and executing to launch it, the install encounters an error and prevents it from proceeding with the installation.
Causes: System files or processes currently in use by the OS are the likely culprits. Also, check the vendor's website for applications installed and verify they are 10.11 compliant. Some apps have yet to make the upgrade to supporting 10.11 and may be affected by new technologies in El Capitan, such as System Integrity Protection (SIP).
Solution: A simple reboot (or shutdown) may be required when it comes to hanging system files or processes. The action will clear out any task requiring the use of those files/services. Another possibility is to power down and then power up holding the [Shift] key. This will enable Safe Mode, which loads the OS without extensions. If the upgrade proceeds, then an unsupported app is probably the cause.
2. Spotlight performance trouble
Symptoms: Spotlight has gained even deeper integration with OS X and web services, which helps make searches that are nimble and informative—until their not. Spotlight is supposed to report back information from dozens of sources, but when it doesn't or it's limited in scope, that's a problem.
Causes: Spotlight maintains an index (database) of information that it catalogs. If the index becomes corrupt (possible, but not uncommon) or if the system is still indexing due to the upgrade (most common), then Spotlight will appear to be slow to respond.

Before you install an ad blocker, do your research to make sure it has the option to truly protect you from all ads. Another potential problem is that the ad blocker you use might actually block important non-ad content, such as retail shopping carts or flight booking engines.

Solution: The first thing to check is what exactly Spotlight is set to index by going to the Search Results tab under System Preferences | Spotlight. Only checked boxes are used by Spotlight—all others are ignored.
Does Avast For Mac Work On El Capitan
Once the settings have been verified, check to ensure Spotlight isn't currently indexing by clicking on the Spotlight magnifying glass in the menu bar. During this time, it's best to let the computer complete the task.
If the issue still persists, the database may be corrupt and require a reindexing. To perform this, launch Terminal and enter the following commands, one at a time:
mdutil -Ea
mdutil -ai off
mdutil -ai on
The first command will effectively delete the current index, while the second the third commands turn off Spotlight and turn the service back on again. Immediately after the third command is executed, Spotlight will create a new database and begin indexing it. Please remember this process takes time (as in hours) to complete and that it's best to not interrupt it until it's done.
3. Microsoft Office 2016 for Mac crashes repeatedly
Symptoms: When opening Word, PowerPoint, Excel, or Outlook 2016, the app crashes and/or the system freezes.
Causes: According to Microsoft, there's a bug (or series of bugs) preventing Office 2016 from launching on Apple computers running El Capitan. Regardless of whether the computer was upgraded or clean installed, the results are the same for Office 2016 users and some Outlook 2011 for Mac users.
Solution: As of this writing, Microsoft has issued a statement regarding the issues experienced by users of Office 2016 for Mac. It's currently working on a solution to fix these problems.
Office 2011 for Mac seems to be working well, apart from Outlook 2011, so that may be a possibility for users who are able to downgrade. Additionally, users may be able to continue working temporarily by using Google Apps or Apache Open Office, as both are free and OS X-compliant.
4. 'Application' is not working properly
Symptoms: 'Application X' was working perfectly prior to the upgrade. Post-upgrade, it does not function properly or even load at all.
Causes: The causes for a particular application not loading or working correctly are nearly limitless and beyond the scope of this article. However, some of the more prevalent reasons for application failure in this case would be system file handling trouble, application compatibility, and/or OS limitation/feature changes.
Solution: The best way to go about resolving an issue with a specific application not working in El Capitan is to first visit the vendor's website to verify compatibility. Many vendors have taken the time between beta and public releases to test and properly vet their apps for compatability with the latest version of OS X. Updating applications to their latest versions will typically resolve any outstanding trouble.
5. Setup user account login prompt
Symptoms: After the final reboot of the upgrade process, the user is brought to the logon screen with an account listed as 'Setup user' and prompted for a password to authenticate. Regardless of the password entered, the password box shakes 'no,' and the user is not able to login.
Causes: This is a mysterious occurrence that has been happening very infrequently. While no clear explanation exists as to why it affects so few or the seemingly random nature of the occurrence, it does appear to be some sort of configuration pass that does not fully complete.
Solution: Reboot your Mac or, better yet, shut it down. Power on your Mac and, after going through the boot process (progress bar), it should load the login with your correct user account listed.
This is not an exhaustive list of the issues affecting Apple OS X El Capitan, but it is a good collection of the more well known issues and their respective fixes.
Thankfully, little has been reported regarding system-level issues affecting the usability of the latest OS. Much of it stems from incompatibility issues between outdated apps and the way in which OS X 10.11 handles systems calls and functions. However, if you're finding an excessive number of issues plaguing your El Capitan upgrade, it may be a good idea to backup your data and perform a clean install of El Capitan from scratch. This would definitely maximize your chances at achieving a stable environment by starting with a good, clean foundation for your apps.

How We Tested
To find the best antivirus for Mac desktops and laptops, we evaluate ease of use, interface and performance impact, we installed each AV program on the same Late 2013 MacBook Pro with Retina Display running macOS 10.12 Sierra. It was powered by a 2.6-GHz Intel Core i7 processor and had 8GB of RAM and 70GB of data stored on a 512GB SSD.
We conducted our own tests in July and August 2017 based on how much each antivirus product affected our laptop's performance. To do this, we used our custom OpenOffice benchmark, which matches 20,000 names and addresses in a spreadsheet. We measured how long it took to run a quick scan and a full scan while the laptop crunched numbers in the background.
We assessed how easy each program was to use and the number of useful extra features it offered (including free add-on software). To gauge how effective each package was at stopping malware, we used the results of evaluations conducted in May 2017 by AV-TEST, a well-regarded independent product-testing lab in Germany, and results from other tests conducted in July 2017 by AV-Comparatives, a similarly well-respected firm in Austria.

Anyone with young children at home will find Sophos' parental controls useful, as they allow for remote scans and checks, and let you block sites by category.

Reasons to Avoid
While McAfee's unlimited licenses mean you can support a whole family of Macs (and PCs and Android devices, too), this program's lack of special features (for a paid version) make it hard to recommend. Further, we don't have malware-detection testing scores for McAfee, so its protection powers are unproven.
