• Start your computer has slowed down considerably since the update KB980408 and KB975496

  Not sure if this should be posted in "performance and maintenance", but since these updates, my boot time slowed. My computer is a month and must not already have these problems of law?

  It could be a coincidence and another question, but I'm not sure.

  Any help is appreciated more.

  Thank you!

  Hello wdemetris,

  Thanks for asking for scanning helps here in the Apple Support communities. I understand how it is important to have access to your scanner and am happy to offer help for this.

  As a precaution, we always recommend that you have backups to make sure that all your data is safe. You can perform a backup using Time Machine and an external hard drive. Use this article to help make a backup of your Mac: use Time Machine to back up or restore your Mac.

  Then, in accordance with article help: printer and scanner for Sierra, El Capitan, Yosemite, and the Mavericks macOS software, the HP Envy 4500 e-all-in-one is supported for printing and scanning. The drivers must be installed, but if not, if it please go to the App Store and check the updates tab to see if there are updates for HP. If there is, please install.

  If you have only general questions about how to get your updated scanner in place or how to scan pictures, please check out these two articles: macOS Sierra: implement a scanner & macOS Sierra: scan images or documents. If everything is configured correctly and you still have problems scanning, please visit this help article: macOS Sierra: scanning troubleshooting.

• I can't save analyses after you download Sierra OAS

  I can't save analyses after you download Sierra OAS.

  The "Save" button is grayed out?

  Hello 2014anthony1,

  Thank you for using communities of Apple Support.

  I see that you can not save scans after updating to Mac OS Sierra. I would make sure I can save analysis too, I do a lot of scanning on my Mac. Let's work together and get this problem is resolved.

  I suggest to use macOS Sierra: update or change the printer software, more precisely, that these sections:
  
  

  Most printers are compatible with Mac OS. When you add a printer, Mac OS automatically uses AirPrint to connect to the printer or the printer software downloads (also called a printer driver).

  If you can not use a printer that is already added, or you see not the options you want in the print dialog box, you can add the printer again with different or software to print settings different.

  Add your printer with different parameters

  1. Choose the Apple menu > System Preferences, and then click Printers and scanners.

  2. Select your printer from the list, and then click the button Delete .

  3. Click on the button Add and if a context menu appears, choose Add a printer or a Scanner.

     A dialog box is displayed that lists all Hello, IP, printers directory shared, and open on your local network. It may take a minute or two for your printer to appear.

  4. Select your printer, when it appears in the list, and then do one of the following:

     • Use AirPrint: Click on the drop down menu, then choose AirPrint (or Secure AirPrint). If AirPrint is not on the shortcut menu, the printer does not support it.

     • Use a printer software installed on your Mac or downloaded from Apple: Click on the drop down menu, then choose Select software.

     • The software to print a file on your Mac: Click on the dropdown menu, then select other. Select the file, and then click Add.

  Update your printing software

  If your printer is not how to use AirPrint, you can use Software Update to download the latest version of the software. If you don't do this, you see a message that software is not available when you connect your printer.

  • Choose the Apple menu > App Store, and then click updates.

    Install the software updates that are listed for your printer.

  • If the software for your printer is not available using the software update, you can contact the manufacturer for more information. Maybe it's that your printer is not compatible with Mac OS. To check, see the article Apple Support printer and scanner software available for download.

  If you install the printing software you don't have Apple, printing software can not be updated automatically when you use the software update.

  Let us know if that helps. We'll help you get through this.

  All the best!

• After you download Firefox 4, my Google toolbar has disappeared. The new F4 page has no opinion, etc. to tools at the top. WHY I would risk this again by accepting the invitation to download 5?

  After you download Firefox 4, my Google toolbar has disappeared. The new F4 page has no opinion, etc. to tools at the top. WHY I would risk this again by accepting the invitation to download 5?

  Changes in the toolbars:

  I don't like the changes made to the user interface either, rather than to save toolbar space, they would have much more space with 1/10 the functionality. But the important thing is that it's Firefox and you can customize things yourself. Your complaints about the Firefox toolbars are the top 10 items in what follows and they are quickly fixed.

  You can make Firefox 5.0 looks not like Firefox 3.6.19, see numbered 1 to 10 points in the next topic difficulty Firefox 4.0 UI toolbar, problems (Make Firefox 5.0, or 4.0.1 resemble 3.6). If you make changes, you must be aware of what has changed and what it takes to use changed or missing features.

  hostage to the third party toolbar:

  Why you would bind your use of any third-party toolbar browser, which was never really necessary, and even less be hostage to not update to Firefox. Google has had over a year to update their toolbar for Firefox 4 and changes for Firefox 5 could have been tested for several months. Google has waited very long before for finally stating that they would maintain is no longer their toolbar for Firefox, claiming that it was not necessary, and that the items were in Firefox. Also be aware that the features are also in their own browser that also do not need or use the Google toolbar. Not only is Mozilla open source, but all the information is available to anyone - you can even listen online meetings yourself or wait for a printed reviewa.

  There is no change to the user interface of Firefox 4 to 5 and probably even not through Firefox 7

  Life without the Google toolbar:

  You can read this article, on the basis of assessment of own Google features were already in Firefox and expanded from there.

  • http://KB.mozillazine.org/Using_Google_Toolbar_features_without_toolbars

  Kicking a dead horse:

  The Google toolbar is no longer supported by Google in Firefox 5 and more ', you may be able to get what you want from him for a limited time, the instructions to install the Google toolbar have been posted before that Google has actually announced a fall support.

• I tried to download macOS Sierra for the last hours on my Mac, but it is still holding still to download. Should I download the El Capitan instead? All sites tell me that I should update my Safari.

  I tried to download macOS Sierra on my macbook pro iOS 10 for a few hours and it still has several hours to go. Should I just download the Capitan instead? All sites tell me that I should update my Safari or I wouldn't even through this disorder.

  You must complete the download of Sierra. It is a very large file and will take some time, especially on a slow Internet connection.

• After you download El Capitan, the wheel spins constantly

  After you download El Capitan, the wheel continues to turn and do not have access to the computer.  What should I do?  He turned for 3 hours.

  Hi artfromfl,

  Thank you for upgrading your Mac to OS X El Capitan! If the download seems to be blocked for a few hours, try to force the Mac to shutdown by holding down the power button until it stops. You can then try to leave it to the top in safe mode. Also, please check your internet connection, if you can connect the Mac directly to your router via an ethernet cable, it would speed up the download process.

  Try safe mode if your Mac does not end commissioning

  If the download does not progress in safe mode, you can delete the El Capitan installer in your downloads folder in the Finder application, and then try to download os Sierra instead.  macOS Sierra

  This should put Mac to update without delay at all. Please use the Apple Support communities to post your question. Good day.

• after upgrade to macOS sierra cannot connect to citrix receiver apps

  I use Citrix receiver apps to make my day to day work. The same citrix apps are also accessible via a web browser (Safari) and everything worked fine until the version IE Capitan.

  After upgrade to macOS sierra I can't you connect/launch of citrix apps. I tried with receiver and citrix via web browser as well, but its not connecting.

  Is anyone else facing the same issue or know the fix.

  Earlier, I thought that maybe some problem of connectivity, but after a lot of troubleshooting it still did not work and shows the same error "failed to initialize." (attached image).

  Then clicked on suddenly to mind that I just upgraded my MacBook OS. In order to confirm if his new problem of macOS or anything else, I have installed Windows 10 on vmware fusion and tried to connect to citrix receiver and it worked only! without any operation of additional troubleshooting, it is confirmed that the issue is again macOS.

  So as a temporary workaround, you can use virtual windows OS on top of the operating system Mac OS page sierra to launch citrix applications.

  But apple needs to fix in the Sierra.

  This seems to be, in part, a browser problem.

  Have you tried, since El Capitan or Sierra, another browser?

  And it would move from Citrix to make their applications compatible with OSX.
