How do I partition a micro sd card for use in android phone

I currently have an Android phone running Marshmallow 6.0.

This allows certain apps to be transferred to the card be treating it as internal memory (like a scratch disk);

thereby freeing up storage space on my phone for additional app storage (ones which cannot be moved to SD).

I have a 32 GB micro SD card.

The problem:

Since the SD card is seen as internal memory, the camera will not see it as external storage and will not allow me to save photos or videos to it. It saves to my phone's storage, which fills quickly (4 GB). Defeats the purpose of moving apps to the SD card.

I'd like to partition the SD card, setting up one partition as external storage and the other as internal memory.

The question:

Is this possible to to do on Yosemite? I assume I'd have to format it as MS-DOS?

Connect the SD card to your computer by using an external card reader. Save all the files from your SD card that you want to keep to your computer before moving to step 2. Formatting the SD card deletes all the data off of the card.
1. Note – If you’re using a Micro SD card, please insert the Micro SD card into the SD card adapter that came with card. Connect the SD card adapter to your computer by using an external card reader.
2. Also note – Mac OS 10.6.5 or earlier does not support exFAT format, which most 64 GB SD cards are formatted to. This means that you won't be able to format or use exFAT card on your computer. In this case, we'd recommend either upgrading your OS to 10.6.6 or later, or using an SD card that's already formatted to MS-DOS (FAT) or FAT32 to complete the below steps.
Open Disk Utility. To do this, click on the magnifying glass in the top-right corner of your computer screen. Type “disk utility” in the search box that opens, then click on the “Disk Utility” Application that comes up.
Find the SD card in the left side of the window. It’ll be named something like NO NAME or UNTITLED.
Click the ERASE tab in the middle of the window.
Next, click on the “Format” dropdown menu. Select “MS-DOS (FAT)” if the card is 32 GB or smaller. If it’s a 64GB card, please select “ExFAT”.
A message will appear asking, “Are you sure you want to erase the partition “[YOUR SD CARD NAME]?” Click “Erase”. Now the computer will delete the contents of your SD card and format it. You’re all done.
