  I own the Adobe Photoshop Elements 4.0 and have a new Mac Pro laptop. It does not load the disk. Obsolete, I guess. How updated to match on the Mac with OS inside Mountain Lion?

• How can I connect HP ENVY 110 d411a (white) for the MacBook Pro OSX Lion running through a wi - fi connection?

  And how can I use the AirPrint.

  (I'm not English, sorry for my bad English)

  1.

  Hello

  I bought a HP ENVY 110 d411a (white) on the last day, but I have different problems trying to configure it.

  I did all the settings of the printer and properly installed the CD rom on 2 PC running Windows XP. (All works) I also tried the ePrint and it works without problem.

  Problems come when I tried to implement it in my book for Mac OSX Lion running. I downloaded the "ENVY-110 - series_v12.14.0.dmg" from the HP site, but it seems that the computer cannot detect the printer wi - fi thorugh, even though they connect on the same wi - fi. Reading this forum I also installed an additional update "HP_Scan_for_Mac_OS_X_10.7_Update.dmg" and "support.apple.com/kb/DL907" Also I tried to unstall all and reinstall another time.

  I'm sure that the printer is on the same wi - fi, I know not wi - fi is active, because the other PC I can print and scan, I'm sure it has a regualr IP address, the printer is new (2 days) and my MacBook is updated to the latest firmware.

  What can I do else?

  2.

  My other question is how can I enable the AirPrint? I tried to detect the printer from the phone, but he can't find anything...

  I read that this requires an update of the printer, but I already checked the updates and it says that the latest firmware is already installed...

  Can you help at least with the first point?

  OK, thanks for that.  This problem is with your router.  Your Mac uses Hello (also called mDNS) to find your printer.  If the router does not support this, your Mac will never see it.  It is a common problem with routers provided by the ISP.

  I would recommend that you contact your ISP and either resolve the issue or give you a router that supports mDNS.  Last resort, you can get your own router and just use the modem from the ISP box part.

• Merger of Causes Kernel Panic after updating to Mac OS Mountain Lion 10.8.2

  I've just updated to Mac OS 10.8.2 Mountain Lion (from 10.8.1 precedent) and suddenly my Macbook Air (2011) crashes whenever I run Fusion. I had Fusion 4.1.3. I also tried to install Fusion 5 but seems to have the same problem.

  The application should start and I see VMWare Fusion in the menu bar (but not yet windows), in a few seconds the machine would crash and I get the grey screen "to the death".

  After you reboot the machine, here's the log of kernel panic:

  I had a very similar problem after updating to 10.8.2. What worked for me was starting up in recovery of OS X and under my boot repair disk volume. There are a number of scheduled file system errors. After the reboot, VMWare works again and the system has been stable for the last half hour or so.

• updated my mac pro early 2011 book now really running hot

  I wanted from the upgrade of my mac book pro early 2011 I7 quad core 8 G ram 2T HDD

  So I finally did. I like it, but now my mac runs hot 116 degrees. the fans are running.

  boot time has also more he takes more time.

  I used my mac pro for dj book I also do a video mixer.

  run final cut pro x no problem

  I also do recording on a DAW. never had any problems so far.

  I understand is difficult to test on all models is a solution for this.

  I thought he was going to improve performance, I don't see it seems to take more time during startup.

  How about this circle just turn around.

  I know that you guys try.

  I hope hear from you soon.

  Thank you

  Run programs of type DJ on an Early 2011 MacBook Pro, while also on El Capitan put quite a strain on the machine. Programs of DJ using just the music will pull a use much more memory and CPU than normal, not to mention video mixing as well. That being said, you use a USB jack in a box/audio mixer (like SL3 or Pioneer DJM900) or you use a DJ controller?

  I do not think that 116 degrees is too abnormally warm for the type of stress you put on the machine. I would possibly consider a SSD drive. Not only will improve performance, but because you will have parts in SSD, as you would in a standard hard drive, the machine should run cooler.

• Just updated for mac apple osx 10.8 mountain lion and I cannot scan with my hp Cap 1610 all in one.

  Hello

  The HP Scan Pro is a very old, destined to Mac OS X v10.5 or older versions of the os.

  Don't forget to uninstall any incompatible software by following the uninstall HP under Applications\Hewlett-Pakard program.

  Then restart your Mac, enter print & scan and make sure that the printer is listed... If this is not the case, click on the Plus sign and add the printer.

  Now, try to scan by using one of the methods below:

• Update book mac pro 17 "2009 to el capitan, is it useful?

  I did hear some good thing of those who have upgraded their old Mac to El Capitan. I jst wanted to make sure I don't end up with a lemon after the upgrade. View off the coast for a few years now. I just bought a new MBP 2015 13 "and an iPad pro 12" so that they can synchronize. My old MBP does not recognize the iPad pro. Should I leave it alone, or is - this useful to upgrade the boy.

  Needs at least 8 GB of RAM for adequate performance, unless you plan to use it for the most trivial things.

  Take the leap, you should do is to make a clone of the appropriate internal drive to an external drive bootable using CarbonCopyCloner or SuperDuper and even plain old Disk Utility. Once you have that and confirmed that it works, it store, do the update and test it for a few days. If you don't like it, start from the clone, clean the internal drive and clone the old system, thus returning to what you have now.

  My end 2011 15 "MBP runs reasonably well on model. Of course, to have 16 GB of RAM and a 7200 RPM HARD drive with plenty of free space helps a little. But it can compete on equal footing with the new 15 mid-2015"rMBP, which is at least 3 generations of CPU to come.

• No function of scanning for Photosmart C4280 all one after updating to Mac OS x Lion

  I downloaded the update day and new drivers, either, Apple and also the drivers of support.apple.com noted elsewhere in this forum. and the function of the printer worked very well for a usb connection of airport network, but the scan function disappeared. There is no scan.app in the Hewlett-Packard folder and there was before. In theory, the scan function should be networked through the airport like the function of the printer, but I was never able to get there. Now, no function of scanning even with usb directly to the computer. Please, please help. I'm going crazy here.

  Hello

  First of all, the printer connected by USB thrugh airport should provide print you only the functionality, it provides no functionality of scan.

  As you can find below, only print sharing feature described by specification from Apple:

  http://www.Apple.com/airportexpress/features/printing.html

  Then, while the printer directly connected by USB, you should be able browse Iamge Capture.

  There should not be any folder Hewlett-Packard, the scan functionality provided through Capture of Image as a complete software not available for operating system features.

  Please follow one of the options below to find how to scan using Lion:

  http://support.HP.com/us-en/document/c01910186

  If you are not yet able to scan, install the latest drivers for printer HP package and try to scan the image:

• I just updated my Mac Pro to Yosemite so I could update to LR CC 2015...

  ... and now, when the computer sleeps, LR tries to stop smoking.  In fact, he is apparently trying to shut DOWN the computer.  Wake up, I get a message that the computer could not connect on (or something to that effect) as LR did not leave (because I have to ask questions about a backup when it closes).  I guess I shouldn't ask WTF here... but what can I do about it?  Is not acceptable.  I waited until 10.10.FOUR OS thinking that it was safe now.

  Thanks for listening.  And for any advice.  Ready to go back to Windows.

  Wow - that was hidden!  Thank you very much!  It was set at 25 minutes and I unchecked it.  I guess the Yosemite came like that - I never had the question before.

  When I have a few minutes, I always say the guest to leave LR Catalog backup when I left it, but I won't try to stop smoking when I'm away from the computer for a while during the day and he goes to sleep. (My catalog file is not so small, with more 120 000 images catalogued, even on a fast computer and an SSD, it takes a while.  "And I do a LOT of deletion).

  But Lightroom is absolutely something I couldn't live without!  I love it!

  How should I clean my Mac Pro to give.  I don't know what drives provided with this computer. It; s end of 2011 (15) now underway 10.10.1 implementation. don't know what it started with.   Processor 2.2 GHz core 7; 4 GB memory.  I have 2 install disk version 10.5 but do not know if they belong to this computer or I can use on this computer.

• Installation 10.11.6 El Capitan with 10.6.8 Snow Leopard on old Mac Pro 4.2 multiboot?

  Looking for savvy here advice...  I have an old Mac Pro 4.2 (cheese grater) that runs Snow Leopard 10.6.8.  It is a wonderful workhorse machine, who served me tirelessly for many years.  It is obviously older and slower, but works very well.  I love 10.6.8.  If Apple ever updated the Mac Pro line (I know, probably not... sigh...), I'll buy one and replace this machine.  Until then, I keep doing this work.

  This machine is a beast, has been upgraded with internal hard drives 1 TB three (he also got a couple internal HDs inherited from 750 and 500 MB used for storage).  I have also several external 1-4 to, hip, FW800 drives too.  A host of storage, of course, and should be a lot of options to start on several systems.

  I am generally satisfied with 10.6.8 on this machine, although there are obvious limits to that.  I would get one or two operating systems newer on it, pick-and-choose between them according to the needs, but I absolutely want to/need to preserve the ability to initiate and run 10.6.8 systematically as my operating system on the day the day, at least for now.  Maybe I'll warm to one of the others on this machine eventually, but 10.6.8 must remain usable, install a newer OS on other readers may not nerve there.

  On a year-and-a-half ago, I took a race to install 10.10.3 Yosemite on one of the internal disks.  This doesn't quite work.  I moved, sniffed Yosemite everywhere, don't really like it a lot and went to restart and him switch back to 10.6.8 for a bit.  Initially, it was impossible (from less than I expected, would be the same old process, I have always used, via system preferences > startup disk).  You can read the details of this experience here and more here if you are interested.  This latest attempt to get Yosemite on this machine was a very negative experience.  Yosemite is still there on an internal HD, but I tried not to boot on it since then.

  Now I take another look at this.  What is the engine now, is that I want to update my iPad Mini 3 iOS 10.  But that (update of an iDevice iOS 10) requires iTunes 12.5.1.  And iTunes 12.5.1 requires Mac OS X 10.9.5 or newer - it won't work with 10.6.8.  I'm looking for my options.

  Right now, I have three large internal HDs: HD #1, 2 # HD and HD #3, each 1 TB.

  HD #1 has 10.10.3 Yosemite on this.  I started from this time and have not resumed since.

  HD #2 has 10.6.8 Snow Leopard top.  This is my main operating system and startup of daily drive.

  HD #3 is nothing special about it.

  Although HD #1's Yosemite about that, I have only started from this disc once and hesitate to go back, at least until I can get a way easy and reliable to restart off HD #2.

  I understand that I can also get 10.11.6 El Capitan.  I thought that installing on HD #3.  That sounds like a reasonable to add option, but again, I want to make sure it won't cause problems to switch back to start off HD #2 in Snow Leopard (such as installation of Yosemite on HD #1).

  What is the best way for me to go about safely - preserve the option to start easily in 10.6.8 on HD #2?

  Thanks for the help!

  If you start or restart now Option (Alt) key and calls the Startup Manager, you should be given the choice at the start of any boot disk OS X on any of the readers.

• Mac Pro Sound cutting in and out

  I just got a new Mac Pro (OSX 10.11.6) (3.7 Ghz Quad Core, 16 GB of Ram, Dual AMD D500 GFX, 500 GB Solid State Drive)

  When video editing in Premiere Pro and sometimes listen to music in Google Chrome, the noise stops.  And it seems to be a bit random and sometimes simply minimize windows and change windows sound coming back.  I've dealt with it for a week now and can't really nailing a model, but it seems that if I switch to a different app and use it for a while and go back to Premiere Pro the sound sometimes works again.  This seems to happen in Google Chrome while listening to pandora when I adjust the volume of the sound will just completely disappear for a time seemingly random.

  Also, I'm quite surprised by the slowness of the system seems to be.  Maybe my expectations were off line, but for a 4 000 dollar computer I expect quite easily handle HD videos.  I'm from a Canon C100 video editing and it's quite ordinary 1080 HD video and preview is set to 1/4 resolution, and the system is really slow.  It seems to fall 70% of executives in the Preview Panel and any action I take have as a half second delay on this.  Is this normal?  I have a personal computer at home that I built to about 1 k and do that kind of thing, no problem.

  I appreciate of course any help you guys can provide.  I need to get this stuff flattened and so I can get some work!

  See if a Safe Mode speeds up your Mac a little. Remove the system caches that could make a difference.

  Follow these steps to start in safe mode.

  1. Start or restart your Mac.
  2. As soon as you hear the startup tone, hold down the SHIFT key.
  3. Release the SHIFT key when you see the logo Apple appears on the screen.

  After the Apple logo appears, this may take longer than usual to reach the login screen or your office. This is because your Mac performs a check of directory of your drive to boot in safe mode.

  To leave safe mode, restart your computer without pressing any keys during startup.

• What happens with the Mac Pro (end 2013)?

  Hello!

  I'm Marc Urtasun, Spain. I have a Pro Mac (end 2013) with 3, 5 GHz 6-Core and two AMD over-pants D500. I am an artist and a 3d animator and I always work with 3d, made, video... and I need a more powerful computer now, because on the 3d, Mac users are moving to Windows due to the advantage of the GPU with CUDA...

  I would like to ask two things:

  -are planning an update or something for Apple's Mac Pro?

  -Can I update my Mac Pro 12 hearts? or update with a graphics card more powerful?

  Thank you

  -All those here who know the future plans Apple could not reveal that, because of the NDA, they signed.

  -Yes, you upgrade to the D700, but that requires to replace two wide boards that contain the GPU and other components. You will find the D700, as Apple does not sell to them.

  -The CPU can be upgraded. See:

  https://eShop.MacSales.com/MyOWC/upgrades.cfm?sort=pop & Model = 486 & type = Processor

  However, some app can use more carrots 6-8. Almost none can use all 12 cores.  When one of your apps look at the CPU tab in the activity monitor and see if you now use fully all 6 hearts.

  You have not said how you memory. Memory can be limited. In addition, sometimes the disk i/o is limiting what drive you have and how ae connected

• Should I update my iMac in early 2008 to El Capitan?

  My Mac is older, fairly new sentence for El Capitan, but it still works very well (running OS X Yosemite 10.10.5).)  It has a processor Core Duo clocked at 2.66 GHz and 4 GB of RAM.  I upgraded the HD to a 2 to Hitachi sister a few years ago and I have a 2 TB Seagate external hard drive for my time Machine.  I can't afford to upgrade my Mac any more right now, but I wonder if I should upgrade to El Capitan.  I would appreciate any advice someone who has a similar system specs & knowing El Capitan.

  With all Mac models, 4 GB of RAM is not really enough for El Capitan. At least not if you use to much more than emails and surf the web.

  Our Mac Pro 2008 has 14 GB of RAM installed. El Capitan works smoothly and quickly on it.
