But you do want to open 'Saved Pictures' in Finder.

I also notice you are using the App Store version of Evernote with this comment:
The app store version of Evernote is sandboxed (meaning the OS locks down its abilities more to use resources external to the app itself -- things like accessing external documents).
So you could also try deleting the App Store version and downloading Evernote directly from https://evernote.com/download if the steps above in that Apple support link don't help you.
 
 

Yes - you just won’t be able to edit them is all. 

In the other thread you commented on, you posted some additional information -- this:
So basically, you created a new account and... got a new account. 
You need to sign in with your original account's credentials if you want your original account's notes.

It looks to me like you've zoomed in on the whole user interface -- and that zooming in doesn't resize the Release Notes popup/dialog.
Try pressing 'Ctrl-minus' a few times to get it back to 100%.

95% of my Evernote usage is on the Mac and I don't experience the linking problem that you are having. All my note links keep me in Evernote in the Mac app.
There are two types of links to other notes in Evernote: web links and in-app links.
There are numerous ways to generate either link, but one of the ways is to right click on a note from the note list and you'll see a context popup menu like this:

However, both links show as "green" in the note editor so you can't tell them apart just from looking at them:

If you hover over the link and click the Edit button:

You will see if it's an internal link (starts with evernote:///):

Or if its a web link (starts with https:):

Note that the mobile apps don't open web links in the web browser -- they keep you in the app. However, the Desktop apps will open the web links in the web browser.
It sounds to me like you have created web links thinking that they are in-app links. However, you still get your desired behavior in the mobile app because it doesn't open web links in the web browser.

Here you can see that I've set mine to 22 (because I didn't want to test 100)...

You can change it to whatever number you want by changing a configuration setting in this file located here:
~/Library/Application Support/Evernote/config.json

I do it on a monitor that is very big and so I can make my note window very wide and then that size of cell sticks for mobile as well.
But you can also start with a two columned cell and keep resizing the first column by using the horizontal column sizer and the horizontal scroll bar like so:



And then delete the second column after that.
You can also create a bunch of columns and then merge them all together:
[][][][][][][][][][]x1 will create a one row table with 10 columns, then:   You can do this merge cell trick on mobile too to get a very wide cell.   Unfortunately not.

I think this is it - it's for reminders.
I tested it just now -- hamburger menu didn't have any blue icon. I added a reminder to a note for today and then I got the blue dot. (I don't really use Reminders all that much now since I mainly just use Tasks.)
If you go to the 'Reminders' tab under notes, you should see a blue dot in front of the title of one or more notes. Then if you mark those reminders as done or remove them, you should see the blue dot go away.
 

Nope.
For things like that, I like to paste the URL and then take a screenshot of the site's content and place it below the URL. Even though the screenshot will soon become out-dated, it gives me a general sense of what the link will take me to.

Which version of Evernote do you have? And did it just start doing that?
Also, regardless of version, this doesn't sound like normal behavior and it sounds like a bug that would impact a large number of users. My guess is it's some issue local to your machine. Have you tried restarting Evernote and/or your Mac?

I think it's just a misunderstanding on your part of what backlinks are and how they work.
These two notes here:

have a link somewhere in their contents to this note here:

That's what a backlink is in Evernote and any other application that I have used them.
If you open these notes here:

You'll see that they'll have a backlink to this note here:

 
In short: backlinks show you other notes that have a link to the current note you are viewing.

It's an offline availability status indicator. (You can't interact with it.)
Edit: You can make individual notes available offline now as well as entire notebooks. If you swipe to the left on the note in the note list and click the '...' you'll see how you can make it available offline. You can also access that menu from the '...' in the individual note.

This is just a misunderstanding.
Viewing an excel spreadsheet in-line in a note (like you can view a PDF and images inline) has only just recently been added as a new feature to the Evernote Professional level subscription. You've never been able to view a spreadsheet inline before.
You can still attach an excel spreadsheet to a note and open it with Excel just like you've always been able to.

You just need to change the view type from 'Preview' to 'Title'

And then you get this:

@Mike P posted the solution for Windows in another thread: shift + double click on the green header works for me (https://discussion.evernote.com/forums/topic/144254-evernote-for-windows-1050-feedback)
So I experimented similar with Mac and it turns out that Shift-Option double-clicking on the green header will open it in a new window.
Undocumented anywhere as far as I know...

Here is a hot take: The 'quick note' is not actually the quickest way to create a new note in Evernote.
The quickest way is to use the global shortcut key (by global it means Evernote doesn't have to have focus, it just has to be running). On Mac this is (by default anyway) Control-Option-Command-N.
You can set a preference to start the note with the cursor focus in the title.
Not only is this quicker than 'quick note', it will also allow you to avoid the title of the note being the current date instead of whatever you want it to be.
So you want to jot down a quick note on Mac?: Control-Option-Command-N. Type your note. Command-W (to close the new note window). Done.

There are quite a few threads about even just being able to even add tags to tasks (vs just using the tag of the note). For example:
https://discussion.evernote.com/forums/topic/137958-need-ability-to-add-tags-to-tasks/ https://discussion.evernote.com/forums/topic/142736-tags-for-tasks/ https://discussion.evernote.com/forums/topic/141818-tagging-task-workarounds/ Which -- having tags for tasks seems like something you might need to have in place first if you want to be able to group them in any sort of meaningful way (edit: besides what you can already do). (and I think using the tag of the note doesn't make much sense as a task would have a different set of concepts than a note)
I've seen requests for having a more robust view or window of tasks instead of just the sidebar (and some of that might entail more organization structure around tags). For example:
https://discussion.evernote.com/forums/topic/138588-open-tasks-in-new-window/ https://discussion.evernote.com/forums/topic/141243-evernote-tasks/ https://discussion.evernote.com/forums/topic/140438-make-tasks-viewable-at-a-full-width-not-sidebar/ There are probably more discussions out there that are similar...

Use Advanced Search Syntax: https://help.evernote.com/hc/en-us/articles/208313828-How-to-use-Evernote-s-advanced-search-syntax
This shows the "contains:task, contains:taskCompleted, taskNotCompleted" that MikeP noted and is the document to which Pink is referring.

If there was a performance improvement, I'm curious why you mention the "Bending Spoons" connection? (Do you think that perhaps Bending Spoons is already busy at work "fixing" Evernote's code with regard to performance? Because I highly doubt that is the case. These things will take many months just to sign all the paperwork, let alone mixing work culture and getting people up to speed on anything. Plus by all indications, Evernote has already been busy working on a huge sync infrastructure overhaul -- also now in beta is a multi-user edit in the same note at the same time feature.)
I've personally only ever had less than a handful of duplicate notes in the last two years -- so that has remained the same for me.
I think I have seen a gradual increase in performance though -- but nothing over the last couple of weeks strikes me as significant, but maybe that's just because I've generally had an overall positive experience already.

Nope. Not possible to disable auto-save. Even if you go offline and make an accidental change -- it is going to change it and then sync it once you come back online like Dave mentioned.
To guard against accidental updates on mobile only you can go to Settings -> Notes -> Edit protection and turn that setting on for all notes. You then have to click the blue 'Edit' button or double-tap the note to make a change.
There are several forum threads requesting a feature for Desktop and Web Evernote to have an Edit protection mode like mobile -- or to be able to set individual notes or notebooks to 'Read-Only' -- but those features don't exist now. Evernote has made no mention if they plan to add that in the future AFAIK.
Best you can do for Desktop and Web is to 'Undo' the inadvertent change, but if you only notice it later after you've navigated away from the note and come back then you'd have to restore the note to a previous version in the history (but you have to have a Personal subscription or better for that).

Can't you just use the "regular" note search. It finds tasks with whatever keywords are in the search. I searched in this case for "veranda":

And that 'asd' note had this task with 'veranda' in it:

That singular search also found two other notes with the word 'veranda' in them (but no tasks).

Will you be able to roll back? Yes. You can run them both in parallel like @Pink shared. Some of the new content (Tasks, Calendar integration) can not be displayed in the old version.
Should you expect issues? I don't think so. v10 is a little slower than version 6 on Desktop, but probably not as big a difference as on your Android.
"Since the "check for update" feature is not working," - I think that was by design and it was good a choice. If they would have updated people to v10 through that process there would have been a major reckoning. Plus you can think of it as a brand new version of Evernote -- almost a different product -- vs an upgrade to the existing software.
It was for me and for a lot of others. (I would guess for most). But there are also many that still prefer the old version for various reasons. I also happen to like the UI more in v10 than the old version.
Evernote has become my daily driver for tasks now and since I need to use both Mac and Windows machines, I love that I can have a unified look across both platforms and that my tasks and notes are cross compatible across both. (I was more just a Mac/iPhone user and used an Apple specific task management system before and so I didn't have access to it on my Windows machine.) Having the look and feel consistent with mobile is also very very nice.
There are a lot of good discussions (as well as heated discussions) in this forum with regards to the new version.
The best part is that you can try it out for a bit and see if you like it or not and still use the old one if you don't like the new one (at least for a little while until the old stops syncing).

I haven't thought about this before with regards to fonts (because I almost always only use the default font and size -- and I'd actually be ok if there were no other font options... but that is a topic for a different thread. 😃) so I wouldn't care either way if it kept the same font size or not when adding a new row because in my case it would almost always be the normal default font.
However, I would like the table to keep the cell background color when adding a new row. For example, if I have a table with 6 columns and all 6 columns have a different background color and then I add a new row, those cells in the new row are not colored like in this example:

I could attempt to apply the background cell to each one manually, but that would be too slow! So instead, I can just highlight an existing row, copy it and then paste it into the new row and it will apply all the same cell colors. Click, Cmd-C, Click, Cmd-V. Really, it only takes a second or two.
Similarly, you could copy the previous row, paste it and then select all the text and write over the top of it and it will preserve the font (as long as you only select the whole text and *not* the entire cell) and other properties. A little bit more work for you than if it happened automatically, but less work than applying all properties manually.
Here is an example:

 

I have that same issue too -- from Sept 14th and it's still there!

Of course it is way down in my list of notes and I actually forgot about it until now.
I think you could try going to Preferences -> Application and then uncheck 'Keep a copy of my notes on this device at sign-out', Sign Out, and then sign back in (and re-check that preference if you want)'

Tasks created from the task module get added to your "Default task note" (so technically there are no noteless tasks) -- see https://help.evernote.com/hc/en-us/articles/1500003792141-Tasks-Overview for more info on that. So you could add an attachment or some note info to the default task note (for that task you just added) or you could move that new task from the default task note to a new note (at any time later) and add more info there.
In my case, my default task note is called "Task Inbox":


yeah - this is me too. 98% of my tasks are part of an existing note that has more detailed info regarding the task -- I only have a few in the default task note.
