Hello, BDAqua.

Thank you! I'll be trying out your very clear suggestion sometime soon.

And of course, I did also receive your suggestion at my email address. However, so far, I've also received from you email meant for three posters from the Legacy Networking Community. Am not sure what, if any, I can do on my end.

Sorry,

A duplicate reply.

Hello, BDAqua!

Finally! I did follow all your instructions -- from the Safe Boot, to Repair Permissions, to a reboot at the end. Still had the Bad Font alert!

So I booted up Font Book, validated all fonts, neatly uncovering and "disabling" about eight fonts except for about four not disabled because they were in System files, as cautioned. As to display issues, for example, there was some improvement in my NYTimes On-line website, but still the same alert keeps popping up. The Alert pops up also with Thunderbird, my  email client, but has no effect on email itself.

I'm hoping there may be other suggestions. Surely, others may have also run into this. It's early, but there have been no entries under "More Like This" in this thread.

.

The consequence of any other remaining "bad Font file(s)" is "livable" since it seems more cosmetic than functional -- so I may just have to live with it. The bad font mostly causes titles of articles/reports to be covered by a line of capital "A" each enclosed in a box.

BTW, I  even ran DiskWarrior 4.4, but without much effect on the font problem.

Thanks in advance.

Sorry.  I don't  know what the above issue is about so cannot click on either Recover or Delete.

BDAqua,

With running Validation of all fonts with Font Book, I did disable a number of font files but NOT those marked by Font Book as being in System files -- as cautioned by Font Book. It's quite easy to go back and disable the five or so such bad fonts being in System files, perhaps one at a time to isolate the guilty files.   It's terrific that you know about faulty font files causing the appearance of lines of capital A each enclosed in a box! 

And no, I've not installed any MS or Adobe fonts or any other fonts for that matter.

Thanks for your continuing diagnoses. You're very kind.

I feel like we're on the right track!

BDAqua,

Yes, I've just discovered that:

"Disabling fonts there may make the Mac unbootable, any bad ones must be replaced."

I've also found an older thread "Font Book Issues" by catoox and extensive replies by Carolyn Samit and Kurt Lang, both June 14, 2007 which:

For me at this time, my Font problem Alert will have to wait until I have more time. Disabling fonts did cause more problems than I expected. Fortunately, I've recovered by starting up with a bootable back-up clone from last April 6th. So I'm off and running again. Whew, that was a close call. Doing bootable back-up clones all these years has saved my skin on two occasions now - well worth the back-up chore routine.

Thanks for all your help. This really did help me.

Raymon

BDAqua,

Thank you.

Except for your first four font files:

._HelveLTMM

._Helvetica LT MM

._Times LT MM

._TimesLTMM

we have the same set of remaining 32 font files! Can the missing first four files explain my font problem? And if so, how do I obtain and add them to my Library?

Raymon

I'm back to finding the solution to the Font Alert problem.

I've opened Terminal but have had no luck with the Terminal commands.

Is there a space between  cd and /System/...

Is it:

cd /Systems/ ...   or

cd/Systems/ ...

Also, in:

ls -a

is that first character

lower case ell?

upper case eye?

Thanks!
