new message window in Yosemite Mail is way to big for a small screen

I had the same issue - I found this fix:

• go to mail > preferences > signatures.
• In the middle box which shows the 'name' of the signature, the system seems to automatically populate this with the entire string of text from the right hand box where you type in your signature text.
• Click on each of your signature names and go in and find the end of the name (which can take a long hold of the right hand arrow key to get to the end if you have a long signature)
• Delete this back to only being one or two words long
• Do this for each of the names is you have multiple signatures
• Exit and restart mail.
• Restart mail - The width of the Signature selection box in the new message window will now be much shorter to correspond to the longest signature names you entered earlier - and this lets you reduce the width of the new mail window.

Thank you Beroli,

Your advice is appreciated, I've managed to resolve this annoying persistent issue using the "work-around" suggested, although, not with out difficulty

The copied signatures [Mail-Preferences-Signature] were only validated following a system restart

Interestingly this issue has been an irritation for some time, I expressed my displeasure to Apple in a Beta testers' feed-back message accusing them of behaving like Microsoft ignoring the related coding flaws which continue to be perpetuated

Thank you again

Blessings

Hi ..

Click the bottom right corner of your Mail window then hold down the arrow then drag to the left to make the window smaller.

Then quit the Mail app.

Then relaunch the Mail app to see if the window size is correct.

I have this same problem on a 15 inch macbook pro (bought earlier this year).

i have the same issue both on my macbook pro 13" and my imac 27" late 2009. In both cases i made a clean install

I have exactly the same problem whether I'm replying or creating.

In the "header" of the email I see the "From" field and the "Signature" field - and it seems the signature field is creating the width.

Can't change the width only the height.

Yes I just removed my signature completely and it now can be resized.

I wrote out my signature again and all is fixed.

Thanks!

Hi

I can do the first part - get rid of my signature, re-size, close email and restart. But when I put my signature back I then get the very wide screen again which I can't re-size.

Is it because I'm cut and paste my signature or I am I missing something?

Thanks

Yes it's because you are cutting and pasting.

Don't do that.

Just type it out again and avoid having a long signature that spans over the page.

Less is more anyway as they say. 🙂

Thanks

Everything working OK now - when you have to put in so much about privacy, virus checking, confidentiality etc.etc. - the signature takes up more space than the email itself!

Let's hope Apple sorts this out quickly because having to cut and paste the signatures in to emails and resize windows is definitely a bug that needs sorted and far form idea for those who need to have legal statements and privacy policies on our emails.

Until then I will make sure the rest of the 20+ people in the office using Macs don't upgrade to this OS version.
