Thank you for your prompt response!

Some of my font tests were done some weeks ago before I had a good handle on the issue, so I don't remember the whole list of fonts I have seen this error with. I was able to verify today the issue using a couple of "scribe" type Hebrew fonts, KeterAramTsova.ttf and TaameyFrankCLM-Medium.ttf. Using Web Inspector I verified that my "normal view" is using Ezra SIL (as EzraSIL.otf, I believe; I also have SILEOT.ttf and SILEOTSR.ttf on my Mac).

For the EzraSIL examples in your two screenshot attachments from Mojave:
a) for the &#x05d9;&#x05bc;&#x05b4; (yod-dagesh-hiriq) sample, the screenshot is different from what I see on High Sierra. It looks correct.
b) for the &#x05e9;&#x05c1;&#x05bc; and &#x05e9;&#x05c2;&#x05bc; (shin/sin-dagesh) samples, the problem is with the next vowel point attached to the letter. For example: &#x05e9;&#x05c1;&#x05bc;&#x05b8;

One of our developers has a machine with Mojave. We just brought up our Genesis 1 file on that device. Apparently whatever you did in Mojave has fixed the Hebrew display issue.

So we can advise our Mac clients with the display issue to update to Mojave. That is great news.

As my initial report mentioned, we are not seeing the problem on the current iOS on the iPad, but it is an issue on the current iOS on the iPhone. Are you able to give any information on when your fix will be available on all platforms?

Thanks again
