My Epson Perfection V500 photo scanner stopped working when I upgraded to Yosemite. The only scanner available is my Epson All-in-One.
I installed the new Yosemite operating system even though I was afraid something bad would happen. Well. it did. I can no longer scan photos using my photo scanner. I have updated all the drivers and it is still not working. I have an Epson Perfection V500 photo scanner, as well as an Epson WorkForce 845 all-in-one scanner, printer, copier. The 845 is on the network. The V500 is connected to my computer. For some reason, I keep getting the error that my V500 is not connected and when I try to add it, my mac does not find it. I know it is there. It was working before I upgraded. Help
You may have already done so, but if not...
Try a different USB cable.
Reboot your computer
Launch Disk Utility (in the Utilities folder) and Repair Disk Permission
in the left pane, click once on the name of your hard disk
in the right pane, click on the First Aid tab near the top
under the blank window, click the button "Repair Disk Permissions."
Afterward, click the "verify disk" button and it will check your hard disk.
Now, try your scanner...

CS5 Photoshop stopped working when I upgraded to Yosemite how do I proceed from here?
CS5 photoshop will not open in Yosemite, Illustrater and indesign are still working together with acrobat... is there a way forward, or is the situation a total loss?
Reinstall the programs.

Need scanner App for Dock. I have Maverick 10.9.5 and Epson Perfection V500 photo. My present app 3.7.1 won't work. Otherwise I have to go into System Preferences every time I scan to Select to switch from the Printer. Thanks for help.
You might give VueScan a try. It should work with your scanner. There's a demo version that you can use initially.

After upgrading to Mavericks I find that the Epson Scan software will no longer run so I cannot now use my Epson Perfection V500 Photo scanner. Is there a solution to this? If not can I delete Mavericks and go back to Mountain Lion?
Hi...
Epson is working on new drivers / software for this scanner.
Until then, you can perform basic scanning from Image Capture.
Or go for 3rd party app. like vuescan.

Internet Explorer stopped working when I upgraded to Parallels 6
I am fairly capable with computers and software, so your direction to a helpful resource would be appreciated if you don't know specifically how to address my problem.
I am new to Apple as of this past April and I am still adjusting from the PC world. However, many of my programs still need Windows and one on-line subscription requires Internet Explorer. I installed Parallels and Windows 7 on my MacBookPro.
Internet Explorer 8 stopped working when I upgraded Parallels from Version 5 to Version 6. It gave me an error message and did not open. IE8 had worked just fine on Parallels 5. My inquiries to Parallels went unanswered. Nor could find a solution on the Parallels website or the internet, in general. I downloaded and tried to install IE9 Beta from the Microsoft website when I saw it offered when I tried to find a solution to my IE8 problem on-line (Safari still works). Now I receive an error message "Internet Explorer did not finish installing". But, I am unable to finish its installation or remove it so I can start over.
Any ideas??I think your problem is specific to Windows. You would have better luck in Windows-specific sites such as this one: http://support.microsoft.com/gp/pcieintro

How do I find out if my 'non apple' paid apps will stop working when I upgrade to iOS 5?
I have downloaded apps from both apple and other developers.
I have paid for some of these apps.
Since there are numerous apps that I use, is there a generic way to know for sure on whether the apps will still work when I upgrade to iOS5?Unless the problem was caused by abuse or other accidental damage, Apple will exchange your in-warranty iPod with a refurbished one at no cost. Make an appointment at the Genius Bar of an Apple store for the exchange.

USB scanner stopped working after PC upgrade
I have HP Officejet 4500 all in one printer. It has both USB and ethernet connections.
This week I have upgraded all PC components (so everything is new) except SSD drive so that I was able to continue where I stopped working.
However, my USB connection with printer stopped working.
First of all, I need to say, that I had to make scanner working over ethernet, so now my printer/scanner works without USB, but:
1. what may be the reason to stop USB connection working?
scanimage -L has usually expected output:
scanimage -L
device `hpaio:/usb/Officejet_4500_G510g-m?serial=CN141F219005CQ' is a Hewlett-Packard Officejet_4500_G510g-m all-in-one
but sometimes:
scanimage -L
and sometimes:
scanimage -L
device `hpaio:/usb/Officejet_4500_G510g-m?serial=0' is a Hewlett-Packard Officejet_4500_G510g-m all-in-one
When I try to scan over USB:
scanimage --format=tiff > test.tiff
scanimage: open of device hpaio:/usb/Officejet_4500_G510g-m?serial=CN141F219005CQ failed: Invalid argument
sometimes it stucks and sometimes:
scanimage --format=tiff > test.tiff
scanimage: open of device hpaio:/usb/Officejet_4500_G510g-m?serial=0 failed: Invalid argument
I have tried all steps on https://wiki.archlinux.org/index.php/Scanner site. I remind, that on the old PC it was working correctly. The problem appeared after upgrade.
2. The output of lsusb is:

I don't have any such problem with rear USB.
All other USB devices work with front USBs. (wireless mouse, USB external HDD, USB CD/DVD, bluetooth dongle).
Can anybody explain me these issues please?
Thanks a lot.This is the full output of lsusb -v :

The cable is quite long. It has about 1,5m. Unfortunatelly, I don't have another cable to test it. Strange is, it was working before.... -
Why does iTunes stop working when trying to connect to the iTunes Store on PC
Everytime I try to go into the iTunes Store on my Windows 7 PC I get a popup that says "iTunes has stopped working, Windows will try to find a solution to the problem."
I wonder why this is happening and I just updated to the new iTunes version about 10 minutes ago (I had this issue with the previous version too.) What do I do?I don't believe it's just you. I am having an issue with iTunes myself on both my iMac and MacBook Pro. The iTunes store won't load as far as viewing my account info or trying to download previous purchases.

Intel Rapid Start stops working when RAM upgraded
I have a brand new ENVY dv7-7212nr notebook running Windows 8 64-bit.
This machine has Intel Rapid Storage Technology which caches hard disk data (I think on the 32GB SSD) and Intel Rapid Start Technology which stores active memory in the SSD cache (I think) when the computer enters a hibernation state.
The first thing I did was upgrade the RAM from 8GB to 16GB. It works fine, but then I get an error message "your system does not appear to have intel rapid start technology enabled."
HP provides very little information on this, basically none. I assume the memory is being cached on the SSD, but I don't know how to verify this. Also I notice that acceleration is not enabled under the Rapid Storage Tecnology applet for either drive.
I called tech support twice but the techs knew nothing about upgrading RAM beyond the usual and couldn't get it to work either.
Does anybody even know exactly how the SSD is being used in my system? That would be valuable information to me.
Thanks in advance!
This question was solved.
View Solution.Thanks for reading my reply.
The "little SSD" is still a drive and not a chip, although you are right that it is little and it is attached to the motherboard. It is little because its form factor is not the typical 2.5 inch size but what's call "mSATA". In fact, the service manual for this dv7-7212nr laptop shows you how you can remove and replace or upgrade this mSATA SSD:
Below is a comparison of how small the mSATA form factor is to other drive sizes (from Left to Right: mSATA, 1.8", 2.5", 3.5"):
So if I want to replace the mSATA 32 GB SSD with a 64 GB SSD, I would have to get a mSATA SSD, not the typical 2.5" ones. So for this dv7-7212nr laptop, there can be 3 total drives installed: one in the mSATA slot and two in the 2.5'' drive bays. However, the default configuration as sold by HP only has one mSATA 32 GB SSD and one 750 GB SATA hard drive, with the remaining drive bay empty.
This dv7-7212nr laptop does contain all the latest (and perhaps more complex) technologies and HP probably does not expect the typical user/consumer to go and muck around all the default settings. However, if one is curious and willing to make the effort to learn, the material is just a google search away.
Here are the instructions for setting up Intel Rapid STORAGE Technology (aka Intel Smart Response Technology): http://download.intel.com/support/chipsets/sb/intel_smart_response_technology_user_guide.pdf
For this dv7-7212nr laptop, you can ignore steps 1-4 because the BIOS is already configured properly from the factory (unless some changes were made by the end user).
Here are the instructions for setting up Intel Rapid Start Technology:
http://download.intel.com/support/motherboards/desktop/sb/rapid_start_technology_user_guide_v11.pdf
For this particular laptop, ignore steps 1-7 but it is important to do this first: set up Intel Smart Response Technology as above, making sure to allow enough space on the SSD for a hibernation partition that is equal to or greater than the total size of RAM installed. Then follow steps 8 to the end of the guide. It is important to set up Intel Smart Response before Intel Rapid Start because Intel Smart Response will destroy all partitions and data on the disk (if you set up a hibernation partition for Intel Rapid Start first, it will be removed when you set up Intel Smart Response).
I have successfully ENable and DISable these technologies on my laptop using the above guides (with my modifications). WARNING: back up all data before trying any of this.
In your case, I agree that you can also disable Rapid START and just use the whole SSD for acceleration along with the 16 GB RAM upgrade.

Epson Perfection V500 Photo Scanner Drivers
I receive this message when I try to activate my Epson Scanner under OS X 10.9:
"You can't use this version of the application "EPSON Scan.app" with this version of OS X.
You have "EPSON Scan.app" 3.2.4"
When I go to the Epson site to download the proper drivers, it says I can only download the update from the Apple Store using Software Update. When I run Software Update it doesn't show any updates for the Epson scanner.
How do I get the proper update?
Thanks,
GeorgeThis is what came up:
On the link - http://support.apple.com/kb/ht3669
It does say:
Important: Use Software Update before connecting a printer or scanner. This updates your Mac's database of the latest supported printer and scanner models. If you don't use Software Update before attempting to connect a new printer, you may not see available software when you connect your device. -
Why does iTunes stop working when I try to type the album name in to submit cd track names?
I have a cd that I'm trying to separate, but whenever I try to type the album name in the submit CD track names box, iTunes freezes, then quits working. Why is it doing this and what can I do to stop it?
Does it happen for any slideshow? Or only for one slideshow with certain images?
Does iPhoto also freeze for a new iPhoto library, if you create a new library with some test images?
If iPhoto only freezes for a certain slideshow, check, if it is one of the photos or videos, that is making the slideshow freeze. Create a new slideshow and add the images one by one, to fnd the one, that cannot be played. Remove it.
If iPhoto only freezes with all slideshows in your current library, repair your iPhoto library. It may have been migrated with permission issues. How did you restore the library, after you wiped your mac and clean-installed?
To repair the library using the First Aid Tools, see Old Toad's post here: Rebuild iPhoto Library, Version 11, see "Fix 1". In your case, I'd start with Repair Permission, the Repair database. Apply the other fixes, if need be.
Post back, if the repair does not help.

AlChemy stops working when Xonar is installed in the same system as X-Fi?
A while back I tried to use an X-Fi Prelude and Xonar D2 in the same system. For the most part this worked, however AlChemy would no longer allow hardware sound in various games on the X-Fi. The results were the same whether DS3D-GX was turned on or off on the Xonar. Another user on a forum I frequent has been able to replicate the issue with a Creative X-Fi and Xonar Essence STX. Can someone suggest what might be happening and hopefully let me know if there is a work-around?
Try older (year+) xonar drivers. Xonar and X-Fi worked fine for me back in 2009. Recently I re-inserted Xonar with newest drivers for some testing and discovered same bug. I think this may have something to do with more agressi've/reckless hooking in GX service (HrMsg), even if GX disabled in Xonar's CP. Killing this process with task manager seems to fix Alchemy.
