keys on one side does not not after installing sierra on my mac pro book

Hello dssheorey,

Thank you for using communities Support from Apple. I have a problem with your keyboard after updating is not what you expect. The good news are the following steps will help to solve your problem and get your keyboard working properly again. First, start by resetting the management system (SCM) controller on your Mac:

Reset the management system (SCM) controller on your Mac.

If you still having the problem after resetting the SMC, use safe mode to start up your Mac so that it performs certain checks, remove files from the system cache, check your startup disk and trying to fix problems if necessary directory. Sign in to your account in safe mode and test the issue again. Then restart normally and test again to see if this problem is solved.

Try safe mode if your Mac does not end commissioning

    You can make a color hex "pipette" very fast easy on a Mac.

    First of all, download this:

    http://wafflesoftware.NET/hexpicker/

    It adds the functionality of hexadecimal color to ColorPicker.

    Then open the Script Editor and enter the two words: choose color

    Save as an application (this creates a stand alone ColorPicker).

    Launch.

    Select the mirror of ColorPicker icon, the cursor and click anywhere to get a hexadecimal color value.

    I think that there is probably a way to make this app always float. If someone could put the AppleScript for this, I would be very happy.

    I hope this helps.

  • The mouse and the keyboard doesn't work do not after Windows 7 update

    I have Windows 7 Home Edition.  My CPU is the last Windows Update during the night, now the keyboard and the mouse do not work.  I rebooted and unplugged both several times.  I go back to my login screen, but I can't do anything from there.

    I prsume your keyboard is USB?  If you can find a friend who has an older keyboard with a PS/2 connector, you can try this, F8 again and select last last known good configuration.

    There is no updates yesterday in itself, because I have them on my PC (I hate the 2nd Tuesday of the month because I run around the House like a crazy woman by ensuring that 1 Vista 64-bit, 2 Server 2008 R2 64-bit, 2 Windows 7 32 bit and Windows 7 64 bit 4 are all downloading correctly and restart if necessary.)

  • Magic keyboard doesn't work don't perfectly with Mac-mini mid 2011

    I am running the latest version of El Capitan (OS 10.11)

    The system version: OS X 10.11 (15A279b)
    Kernel version: Darwin 15.0.0
    Apple Bluetooth software: 4.4.0f4 16320

    These correspond to the requirements of Magic Keyboard (Mac computer compatible Bluetooth with v10.11 OS X or later) according to Apple documentation official http://www.apple.com/shop/product/MLA22LL/A/magic-keyboard-us-english

    If I followed the instructions to connect the keyboard up via Thunderbolt, the keyboard works partially. I can type via Bluetooth.

    However, I can't use the volume buttons to control the sound. When I try to assign or reassign the buttons, I discovered that I can't 'see' the keyboard in Control Panel.

    So, I find it very strange and of course disappointing. I can use Bluetooth, but not make the best use of the characteristics of the material. So sorry to say this, but it feels more like Linux where drivers regularly can make full use of the material and do not like Apple where it should all be integrated from top to bottom.

    The ideas or support would be appreciated.

    Ray

    PS I have the same problem with the new Magic Trackpad. So it's more than 200 euros for the minimum functions

    If I followed the instructions to connect the keyboard up via Thunderbolt,

    It be USB to lightning, Thunderbolt.

    Check that this block is not checked. You can also try to check it out and then unchecking it.

    PS You should also upgrade to the current version of El Capitan, 10.11.2, build 15 c 50. Updates cover a lot of previous bugs and problems. "15A279b" is not the latest version.

  • Customer light HP t5325 doesn't work don't not with VMware View 5

    Hello

    I recently got a slim Pro HP t5325 customer for testing with VMware view 5. I ve the thin client to the latest firmware update:

    http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en & cc = us & prodTypeId = 12454 & prodSeriesId = 4063703 & prodNameId = 4063704 & swEnvOID = 4030 & swLang = 13 & mode = 2 & taskId = 135 & swItem = vc-99080-1)

    who has the view 4.6 customer and according to the VMware compatibility list:

    http://www.VMware.com/resources/compatibility/PDF/vi_view_guide.PDF

    It should work with view 5. But when I try to launch the client and connect to your desktop from view, he asks just a super quick message (which I don't see) and then it brands the "active" session, but it doesn't open anything . View 5 Client on my laptop works very well and I m able to access the same desktop VM.

    My current setup is:

    • vCenter server 5
    • ESXi5
    • VMware View 5

    What Miss me? Any help would be appreciated.

    Thank you!

    David

    Hello

    I had the same problem this week. He is not related to view 5, same problem exists also with 4.6.

    The problem seems to be that when you try to open the connection, the client calls a /usr/bin/view_wrapper.sh script and this script does NOT run with user privileges? However, if you switch to admin and then open the connection this script works well. You can test it by opening the X terminal in the thin client, then the su user and try to run the script manually /usr/bin/view_wrapper.sh start at 0 and you will get a prompt for sudo.

    I tried to add the useraccount 'user' in/etc/sudoers and allow that user rights sudo for view_client and view_wrapper.sh programs. Did not help

    If you add the user 'user' to the root group, connection opens fine but then you let the open thin client for the standard user to mess with.

    Quite a bug in the software? They don't do any test before releasing these?

    HII,

    I have vostro 3460, after installing wireless window 8 works do not, I downloaded the driver wireless dell site, but its not to proceed with the installation

    Please help me

    OK, I found a solution

    -Download the 1 x 1 Dell Dell Wireless WLAN 802.11b/g/n (2.4 GHz), the Bluetooth v4.0 + HS driver (link: Network_Broadcom_W7_A01_Setup-WTD28_ZPE)

    -Run the file. It will extract to c:\dell\drivers\WTD28. Then an error/warning occurs and that execution is aborted.

    -Open the Windows Device Manager. Find the missing element of WLAN with the yellow exclamation point (here name like 'Network controller')

    -Update the driver manually and use c:\dell\drivers\WTD28 as the path of the driver. It will automatically install and start working.

    Hope it helps someone

  • LINKSYS WRP400: Voice recorded but the number doesn't work don't no (not in service) (no SIP response)

    Hello everyone,

    I have a weird and frustrating problem with some Linksys WRP400 and I hope you can give me advice.

    Long story short: the voice on the WRP400 line keeps stop working, even if it is registered on my SIP PBX. Only a reboot of the router or a stop put on the line temporarily fix the issue.

    Let's add some details: I had a lot of WRP400 installed and running, and not all of them have this problem. They all have the same configuration.

    I tried to work around the problem, reducing registry expires 3600 to 1200, defining to call without Reg and years call without Reg, setting on restrict the IP Source address and reset daily at 05:00. It doesn't seem to help.

    When the problem occurs, if I call the voice line number I get an error "the number you have dialed is not in service" or similar. Sometimes my clients said they can make an outgoing call, while the problem is still on, but more often, the line is totally silent on the outbound road.

    On my SIP PBX, I see that the number is regularly recorded, with the right timing.

    If I do a sniff of Wireshark on my SIP PBX, I see some regular "ask: INVITE sip:[email protected]/ * /: 5060; transport = udp, with description of session' a PBX to the router but the router never answers.

    If I reboot, the vocal line to re-register and start working again.

    I have attached a screenshot and the Wireshark Sniffer.

    I use the 2.00.32 latest firmware.

    You have any advice? It becomes an annoying problem and I am groping in the dark.

    Best regards

    Maurizio

    PS: Should I I asked Belkin or is it always in the right place?

    http://about.me/mauriziotroilo

    Hi, we use the WRP400 of the years and the voice module has always been problematic.

    I have a theory on this problem: I think that the safety function to "Restrict the IP Source address" crashes after a few hours of regular work and it filters all incoming SIP messages.

    You can confirm this idea by turning on the trace of the sip. In my case the trace shows all SIP entering until the reboot request.

    Can I ask you how many CPES you have?

    What is the frequency of this problem?

    In our network, we have about 2000 installed platform and we must restart on unit 2-3 per day.

    Kind regards.
