Mac Clean Tips
The new version of Mac OS X, the El Capitan will be released earlier than normal on this Sept. 30, which keeps the same overall look as OS X Yosemite, but comes with a handful of new features. This is a good news for Apple users because they can enjoy both the new OS X and iOS 9 this September, which work seamlessly just as Yosemite and iOS 8 last year.
Every new update comes with new issues. Just as the early release of iOS 9 that brings many problems to iPhone iPad users, the El Capitan is no exception. In this article we will look at the most common problems with El Capitan, including problems with Wi-Fi, VPN issues, problems with printer, etc.
Question 1. Show a “download failed” Message
Direct to release a new operating system which run on the Apple server is always very large. So do not be surprised if the download is slow or even temporarily stops. A day or two later it should run much faster. And you can try to use a wired Ethernet connection that may fix most of the issues. Generally speaking, a hardwired connection is a lot more reliable than a wireless connection, so it’s always best to opt for Ethernet whenever you can. For newer Retina MacBook Pros and MacBook Airs don’t have Ethernet ports, try to get adapters that allow you to plug in an Ethernet cable into one of the Thunderbolt ports. If you have no idea of how to upgrade to Mac OS X El Capitan, here is how: Go to App Store to download Mac OS X El Capitan > After Mac OS X El Capitan downloaded, the El Capitan installer will open automatically > Click Continue and follow the onscreen instructions.
Question 2. El Capitan Gmail Bug in Mail App
Some Mac users have found that Mail app behaves strange after updating to OS X El Capitan particularly with Exchange and Gmail accounts. Since the launch of Mac Mavericks both Gmail and exchange accounts are not working correctly in the native mail app client. Follow the steps to fix the El Capitan Gmail bug in mail app.
Open default Mail app on your El Capitan, then from the “Mail” menu and go to “Preferences” option.
Go to the “Accounts”, and select the email account that has problems, then click on the “Advanced” tab.
Find the box named “Automatically detect and maintain account settings”.
Now check or uncheck it – then re-launch Mail app.
Question 3. Mac Won’t Start
Mac Won’t Start
Nothing can be more frustrating than turning on your Mac but only to find that it won’t start up. Instead of seeing the Finder, you see a blue or gray screen, an icon of a broken folder, a kernel panic, a flashing question mark, or a computer that just sits there. Many MacBook users maybe encounter MacBook pro is slow to start up El Capitan. And even though choosing restarting option, Mac won’t restart, either. In these situations, you can take the following steps.
Make sure that you have a good connection from your Mac to the wall outlet by confirming the power cord.
If the wall outlet is working and you still have no power, try another power cord or adapter. If it works you may need a replacement cord or adapter.
Disconnect all accessories that are plugged in to the computer.
If you recently installed any of the solid drive, hard drive, make sure that they are installed correctly and are compatible with your computer. If it is possible, reinstall the original memory or drive into the computer to find out if the behavior persists afterwards.
If your mac still won’t start up after trying each of these steps, you may need to visit an Apple Store.

Question 4. Error Message “Downloaded .app is damaged and can’t be opened”
Mac OS X security by default does not allow all .app extensions to be installed. When there is an error message “Downloaded .app is damaged and can’t be opened” pops up, sometimes this is just a security issue that can be corrected.
Go to the Apple icon, and chose System Preferences.
Check Security & Privacy settings in General tab under “Allow apps downloaded from”.
Check the box beside the option of “Mac App store and identified developers” or “Anywhere”.

Question 6. El Capitan Wi-Fi Issues
After updating to OS X El Capitan, you may have trouble that Wi-Fi is disconnected when Mac goes to sleep. It’s hard to offer a single solution to the El Capitan Wi-Fi issues. You should start a Time Machine backup before you trying the solutions in the following.
1.Remove Bluetooth
1. Go to Finder > Click on the File menu > Select New Finder Window > Click on your Mac’s icon.
2. Open Macintosh HD > Open Library > Click Preferences > Find the file called “com.apple.Bluetooth.plist“.
3 .Move it to your desktop > Remove it from the Preferences folder by dragging it into the Trash. The Mac will tell you that Finder wants to make changes. Type your password to allow this.
2.Forcefully removing network configuration files
1. From the OS X Finder, hit Command+Shift+G and type in:/Library/Preferences/SystemConfiguration/
2. Within this folder select the following files:
com.apple.airport.preferences.plist
com.apple.network.identification.plist
com.apple.wifi.message-tracer.plist
NetworkInterfaces.plist
Preferences.plist
3. Backup the folder “SystemConfiguration” by copying it to your Desktop.
4. Delete the folder as it sits in /Library/Preferences.
3.Changing Router Settings / Reset Router
1. Try factory resetting (via routers administration panel) or turning your router on and off again.
Changing the network frequency from 2.4Ghz to [2.5Ghz or 5Ghz], or from 5Ghz to [2.4Ghz or 2.5Ghz]. In general, set the Wi-Fi frequency to one other than the one it is currently set to.
Setting one type of Wi-Fi mode, e.g. “Only B”, “Only G”, “Only N” instead of “B/G”, “B.N”.
Many times, on Mac OS X El Capitan, you will also encounter that Mac Internet or Wi-Fi is very slow, and Wi-Fi is connected but no internet at all. Firstly, you should check the speed is using your ISP (Internet Service Provider) to look in your modem or router configuration, as it will often display the actual connected line speed which indicates the maximum that you should be able achieve on the DSL line and with your subscription.
1. Use an Ethernet Cable instead of Wi-Fi
WiFi rarely achieves the speeds that a cable can due to signal loss, congestion and attenuation, not to mention the proliferation of Wi-Fi hotspots configured to use the same radio frequencies, which inevitably causes the available bandwidth to decrease massively.
2. Move the Wireless Router to the right place
If you need to use Wi-Fi for some reason, you should make sure that the Router is in the best possible position with no obstructions. Move the router to a central position in the house (or near where you intend to use it most frequently). Try power cycling both your modem and router.
3. Use the fastest ISP
This is a common sense advice, if you really want the fastest Internet then you need to arrange a suitable premium package with your Internet Service Provider. Check with your existing ISP if you’re eligible for an upgrade, or whether you can change your existing package to a faster one. Otherwise, change to another ISP for some special introductory offers and discounts.
