WiFi says it's working, but it is not
I have a Macbook Air El Capitan 10.11.2 running. Whenever I try to use internet on my home WiFi, for example to check my e-mail or watch something in Safari, it is not just charge even if the WiFi icon at the top seems OK. If I open WiFi Diagnostics and choose help me, it says that my WiFi is working properly and that the internet works so briefly. I have to go through the routine 'Help me' whenever I want to load a Web page or check my email. It is slow and frustrating. Is there a way to fix this? The only solution I found is to use my iPhone hotspot. My iPhone and other devices use WiFi with no problems whatsoever.
Please read this message before doing anything.
This procedure is a diagnostic test. It is unlikely to solve your problem. Don't be disappointed when you find that nothing has changed after you complete it.
The test is intended to determine if the problem is caused by a third-party software that loads automatically at startup or logon, by a device, by a police conflict or corruption of system files or some system caches.
Disconnect all devices wired except those required to test and remove all the expansion cards from secondary market, as appropriate. Start in safe mode and log on to the account of the problem.
Note: If FileVault is enabled in OS X 10.9 or an earlier version, or if a firmware password is defined, or if the boot volume is a software RAID, you can not do this. Ask for additional instructions.
Safe mode is much slower to boot and run as normal, with limited graphics performance, and some things work at all, including an audio output and a Wi - Fi connection on some models. The next normal boot can also be a bit slow.
The login screen is displayed even if you usually connect automatically. You need your password to log on. If you have forgotten the password, you will have to reset it before you begin.
Test in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and make sure you always have the problem. View the results of the test.

How can I fix the "drag and drop" feature in Windows 7? It used to work, but now does not work, for no apparent reason!
What happens when you try? Make sure you drag the icon image and not the text of the name.
If it still doesn't work there are some registry changes that can try to alleviate the problem. But because the changes to the registry are tedious and dangerous, I recommend to leave the system to repair it for you. Here's how:- Type of restore in the search box of the start menu to find and open to restore system files and settings from a restore point.
- Click Next, choose a date before the problem started, then click Next once more.
- This process only takes around 2 minutes and only restores your system files/settings: it will not affect any of your files, documents, photos, emails, or anything else.
If the system restore does not resolve the problem try this to replace missing or corrupted system files. Here's how:- Type cmd into the start menu search box, and then press Ctrl-Shift-Enter to launch as administrator.
- At the command prompt to start the File System Check, type sfc/scannow .

I try to download the 30 day trial of PS and and he says his 'download now', but it's not. There is nothing that's going on, nor is it a file in my downloads. It's been over an hour now and I tried 3 times. If anyone can help?
If you follow the 7 steps you can directly download a free trial here: Adobe CC 2015 Direct Download Links: Creative Cloud 2015 Release | ProDesignTools
If you have a problem from the download, you follow the 7 steps, or your browser does not accept cookies.
the most common problem is caused by failing to meticulously follow the steps 1, 2, and/or 3 (which adds a cookie to your system, allowing you to download the correct version of the adobe.com site).
failure to obtain this cookie translates into an error page displayed after clicking on a link on prodesigntools.com or initiates the download of an incorrect (e.g., current) version.

the Magic Mouse that came with my iMac to work but it does not recognize HP USB Wireless Mouse
the Magic Mouse that came with my iMac to work. I tried to use the HP USB mouse that I use with my MacBook Pro at home, but it does not recognize. I went into the settings but it only sees the mouse Magic Mouse. I tried configuring it as a PC mouse. How to recognize the USB of the computer mouse. I need a HP bluetooth mouse? I can't work with this mouse, it has a funny scroll for it. It is too fast or too slow. Help!
< published by host >
There is no reason why the iMac should not be able to use a USB mouse. With the mouse connected to the computer off the computer tower and turn it back on. Now it doesn't recognize the mouse? If this is not the case, try a SMC reset.
