Apple Motion 5.1.3 and FCPX 10.2.1 crash when using CMYK slider in Color Picker

I have a precise color I need to use and the reference is in CMYK.
I am able to switch the Colors selector from RGB Sliders to CMYK Sliders, but when I try to adjust a slider, Motion crashes, FCPX as well.

Are you too experiencing this? Obviously others do:

Update:
I thought I could workaround this bug by doing this:
Open Textedit, select Format / Font / Show Colors.
That will open the Color Picker floating window identical in all Apps including Motion and FCPX.
Go to CMYK Sliders, and create your colors without crashing, save them in the color swatches (buckets).  Then go back to Motion, FCPX - the colors are there in their buckets, ready to use.
Except that when I pick one of these newly created color swatch, Motion CRASHES.
So no luck...

But then, I had this idea:
Open Textedit, select Format / Font / Show Colors.
That will open the Colors floating window identical in all Apps including Motion and FCPX.
Go to CMYK Sliders, and create your colors without crashing, SWITCH the slider to RGB slider, THEN save your color in the color swatches.  Go back to Motion, FCPX - the colors are there in their buckets, ready to use.
This time, no crash! But, come on Apple, can you fix this please.
From there You can create a new Palette and save and organize your new colors.

PS: I can't find a way to "erase" a color swatch (bucket). It seems the only thing one can do is replace a color with another, but no way to drag out a color to empty the swatch. Has someone found a way? Let me know.
PS update: Drag a color swatch to another and that'll empty it. So basically all buckets can be erased but one.

Update:
Apple has corrected this bug in FCPX v10.2.2. Thanks!

FCPX 10.2.1 Cross Dissolve bug - Luma drop

A one second in duration Cross Dissolve (Look: Video. Ease: In and Out, Ease Amount: 0) applied to a Prores 4444 clip (first clip in the Timeline), in a Prores 442 Timeline playback correctly .

When I Export the timeline to Prores file though, there is a drop in Luma at the end of the fade in the exported file.

FCPX Missing Plug-in (Effect) difficult to track down - pt2

Please Apple make it easy to find a missing Effect or Transition in FCPX.

I'm spending hours pulling my hair and agonizing. It's just untenable having only an exclamation mark over the Event icon to alert you that something is missing.

Some Title is missing...

Some Effect is missing...

Nothing pointing at the culprit Project or Compound Clip. Where to search without a clue?

How about a Timeline tab showing missing Effects? Or make searching for Effects, or missing Effects available in the Browser.

At least missing Media is easy to spot, and then to fix using the Relink Missing Media Files.

How about a Relink Missing Effects Files?

Apple has to make it easy to find missing Effect or Transition. If you think like me, please send your feedback to Apple:

Update:

Ah, ah! maybe this tool can help:

Mac OSX 10.10 Yosemite, Error Message: "The operation cannot be completed because an item with the name ".DS_Store" already exist"

I got this error message trying to do a basic thing: copy a folder from one drive to another.

Not sure how/why this bizarre error is showing up, in any case the workaround seem to be to simply copy again, at which point you're asked the usual: "A folder named ' ' already exists in this location, do you want to replace it with the one you are copying?", click "replace" and off you go.

Premiere Pro CC powerful feature: Import selected Sequences or Bins from another project

Premiere Pro CC Import selected Sequence or Bins is a powerful tool, I wish FCPX had something like this - instead of merging entire Library or Events.

Use Import, and let the user point at the Library, and access all Events, Bins, Collections... And import only the ones selected.

That would beat the cumbersome merging of Libraries, described in a previous post: http://tinyurl.com/lvsqmlp

Yosemite WiFi dropping connection

So I updated to Yosemite and FCPX 10.2, so far so good.
Except that WiFi is constantly dropping the connection. It's driving me nuts.

I've tried this re-ordering of the services within System Prefs/Network/Gear thingy.
"System Preferences > Network > Gear Icon > Set Service Order (Make Sure Wi-Fi is at the top of the list) "

I'll update with results. Hopefully positive.

---Update:

Yep, for me it seems to be working, no more loosing WiFi connection :-)

Interestingly enough, this feature was in Mavericks as well, but Mavericks wasn't dropping the WiFi connection.
