This is a normal Mac, so why isn't mine already "case insensitive"? Perhaps the drive in question isn't the main Mac drive. I am installing as an Active Directory Domain user and the user's "Desktop" is on a network drive. Would it be trying to install there? Is there a way to know if a drive is case insensitive or not?

LATER ...

I tried 'diskutil info /' and got:

Partition Type:     Apple_HFS

File System Personality:  Journaled HFS+

   Type (Bundle):      hfs
   Name (User Visible):Mac OS Extended (Journaled)
   Journal:            Journal size 24576 KB at offset 0x94d000
   Owners:             Enabled

According to a website I found, the first line would have "Case-sensitive Journaled HFS" if the drive were case sensitive. In addition, I logged on as a local user and did:

touch MARK

cat >mark

asdf

asdf

^D

and there was no 'mark' file, but MARK did contain "asdf". So did file mARK, etc. So, my Mac drive must be case sensitive.

Does this therefore mean that Acrobat Pro DC cannot be installed for network users?

EVEN LATER ...

I installed Acrobat Pro DC as a local user. This did, in fact, cause Acrobat to show up in the domain (network) user's Applications folder and I was able to open the program as the Domain user. My main need here is for scanning. Since I did this remotely I do not have physical access to the scanner, so testing that will have to wait until I have physical access. It did, however, list the Brother ADS-2200 in the list of scanners, so looks promising so far. I'll post back after I try scanning something.

After doing some testing ... (this may be more appropriate in a different thread)

I successfully scanned two double-sided pages with the Brother scanner using the Mac 'Image Capture' application, scanning to PDF at 300dpi. That created a perfectly clear, readable PDF albeit not searchable.

I then tried using Acrobat Pro DC both as the network user and as the local user. My settings were: Both Sides, not Optimized, recognize OCR, 300dpi, 24bit color, 2-sided. In both cases it scanned the two pages through the scanner and then I got the error, "An error occurred while running scanned image optimization. Aborting Scanning operation." After which I could not restart Acrobat nor log off without doing a 'Force Quit' on the Acrobat DC process. As noted, I did not have optimization turned on. I also tried turning off OCR, but that didn't matter.

I assume this all should work. Acrobat was downloaded 2 days ago and installed yesterday. Ideas?

I feel like I'm pretty much monologuing on this thread ... more results:

I read on another site with someone having the same problem the advice to go into Options and use the 'native' driver. I saw no Options selection, but I did try dropping down the devices menu and had another device for 'Brother (ICA)'. Not sure if ICA is native or not, but using that device did permit scanning. In fact, the scan interface looked pretty much the same as the Mac 'Image Capture' interface. This time, it did create a searchable PDF and I was able to leave 'Optimized' selected. It was also able to append the scanned pages to an existing file.

This leads me to believe the 'Test Screen Name's link declaring "Update: With the July release of Acrobat DC, we have added the support for 64 bit TWAIN drivers on Mac", might not yet be implemented and that his original statement that "Adobe Acrobat DC does not support Twain drivers on Mac" is probably still true.

But, there is still one show-stopper. Even though I select 'Pages: Both Sides", and select 'Duplex' on the scanners settings as well, it will still only scan the front of the pages. Rather surprising since the Mac 'Image Capture' did scan both sides.

So, unless someone has a solution for this, we will be returning Adobe Acrobat DC for Mac. Unless both sides can be scanned at once we cannot use this in our office.


Hi techOHPRS,

Sorry for your feeling abandoned, I just picked up this thread.

Bit of a background on me: I've used Macs since 1985 and have used scanners since around 1986 or 87 (can't remember for sure but I know it was an Apple scanner.

Over the years I have installed hundreds and hundreds of software titles and multiple versions of some of them (updates and all) and I've never been aware of any case sensitive/nonsensitive issues. Never encountered it. Something is strange about your Mac that I cannot address without examining it. Since you purchased it recently you do have phone and Genius support at Apple. Have you contacted them?

I cannot speak about a Brother scanner, I've never used one. I personally have an Epson (V800 if that matters).

Now before I continue, I have to say that because only recently (as you've discovered) re-added Twain. Otherwise, the only application that the Mac can access to directly with with a scanner is Image Capture. Personally I find Image Capture one of the worst pieces of software I've ever encountered. Because of this, I NEVER scan directly from within Acrobat. I always scan using either EpsonScan (which is OK software) or SilverFast (great scanning software, not cheap, but is best for photography and overkill for text documents).

However, I did use a FujiScan several years ago when I had a thousands pages of texts to use. (Looking at the photo of your Brother, it's the same kind of machine.)

I marveled at the capability of that FujiScan to rapidly go through pages after pages of documents. Because I needed/wanted OCR on the pages I was running them at 600 ppi. It runs slower at that resolution but OCR improves as resolution increases. (If you need to know why please ask. Otherwise I'll assume you already know.)

While the FujiScan could also OCR I found it's performance was pretty dreadful. Not only was the quality of the OCR not very good but the document sizes were ginormous.

What I ended up doing was to fill a folder with a day's worth of scanning and when I left for the day I left Acrobat processing all of the documents within the folder. As you can gather from that comment, Acrobat's OCR conversion is not likitty split. It's slow, methodical, and very accurate.

This can be read as "There is faster, better, cheaper — pick two!"

Also, suffice it to say that I did not encounter any issue with double-sided processing of the pages because I let the FujiScan deal with that (which it did wonderfully).

Also, let me provide a link I did some time back of a blog I did for Adobe about scanning "clean" copies. This does not directly affect you (because of what you are scanning) but it does emphasize how I just do not bother using Acrobat to do the scanning. As you've learned, Acrobat cannot scan anything but relies upon a link between your machine and your scanner to link your software with another piece of software.

From years of watching others deal with this, when it works, great, but it is so fragile it isn't worth it to me to MAKE it work. This goes into the concept of "do you want to get the job done or do you want to do it the way you think you should be doing it?"

I just want to get the job done. YMMV   8>)

You need to format your disk as case insensitive. They always have come that way from the factory, except for one brief experiment during a Mac OS beta, which was hastily undone as many things broke. Including all Adobe apps.

Following up ... I've purchased a Brother ADS-2200 scanner and successfully installed it on my Mac. I've also just purchased and downloaded Acrobat Pro DC for Mac. Problem: when I go to install Acrobat, I get the message, "Sorry, installation failed / Installation on case-sensitive volumes is not supported." Huh? This is a bit shocking. How long have Adobe and Apple been around and working together? Didn't Adobe get it's big start on Mac? I've having trouble wrapping my head around the idea the that Acrobat Pro DC developers didn't know Mac files were case-sensitive. Surely there must be a workaround for this.

What it is?

You can use Adobe Acrobat.

Provided the scanner includes a Mac driver. This is a choice of the scanner manufacturer; Adobe cannot provide them.

Test Screen Name: Yes, I'm looking at scanners with Mac support. So far, the Brother ADS-2xxx series looks good. According to this link: macOS High Sierra (macOS v10.13.x) Compatible Models | Brother a TWAIN scanner driver for High Sierra is included.

Bernd Alheit: According to this link: Plans and pricing: Compare versions | Adobe Acrobat DC Acrobat Pro DC is the only Mac version that supports PDF scanning and editing, and scanning paper to PDF is listed as a NEW feature. Hmmm.

Have either of you (or anybody) actually used a scanner with Adobe Acrobat on Mac? If so, what version of Acrobat did you use?
