No, I don’t think the installation failed for that reason; but I think I remember having seen a similar problem in the forum a good while back, and I think the conclusion was that the download probably didn’t properly conclude, leaving a defective copy of the OCRHelper.
I’ve just searched the forum and here Jim suggests to the user of an m1 Mac that granting FDA to the OCRHelper app may help. I’ve just checked, and on my Intel mac, the OCRHelper app does not have - or need - FDA. And the user sadly didn’t provide information on whether it was that step which solved the problem or not. Worth a try though (but do remove FDA from the OCRHelper app if it doesn’t help).
Presumably you have tried more than one PDF and none works? Is anything logged to the log (Window/Log)?
If this step also does not help, I would suggest waiting the day to see whether Jim provides the solution here, and otherwise opening a support ticket.
From Devonthink.
I have several screenshots that contain text. They are PNG files. I imported the PNG files into a DEVONthink library.
I tried to convert the PNG files into OCR Pdfs directly, and I had this issue. Then I converted the PNG into a regular PDF, that worked.
Then I tried to covert that pdf into an OCR pdf, that did not work
To help track down where the OCR is failing, could you turn on OCR logging, to do this:
Quit DEVONthink
In Finder select the menu Go->Go to Folder, copy and paste the line below and press Go.
~/Library/Application Support/DEVONthink 3/Abbyy
Copy the file OCR.plist (274 Bytes) to this folder.
Restart DEVONthink, if the OCR fails could you send a copy of the log files. The easiest way to do this is in DEVONthink select the Help menu and whilst pressing the Option key select the “Report a Bug” menu item. This will open an email with the logs attached. If you make it for attention of Alan.
That fixed it. I think I know what the problem was.
The DTOCRHelper does not work with M1.
When I double-clicked on the app, I got a message from MacOS indicating that I needed to download and install Rosetta to run the application.
I did not have Rosseta in my Mac because all my applications are M1 compatible, or so I thought…
After installing Rosetta, I launched Devonbthink, and I was able to OCR my pdf file.
My next question is:
is there a way DEVONthink can use the M1 version of the OCR library?
ABBYY are in the process of developing an Apple Silicon version of their OCR library, until that update is released it has to be run under Rosetta. They haven’t announced any release releases dates so I am unable to give you any timeframe for it to be a fully native Apple Silicon application.
If you have a brand new MacBook Pro 2021 beast, and it is just installed and haven’t installed any other Intel-only app, DTOCRHelper will fail because lack of Rosetta 2. Once manually run for first time DTOCRHelper and asked for installation of Rossetta, it went flawlessly.
I installed Devonthink PRO on my new M1 mac, the OCR addon was downloaded and installed but there is no option to made a OCR of PDF in right click menu
DTOCRHelper doesnt throw any error, I have other Rosetta apps
