Installing MacFUSE will not affect Spotlight search capabilities at all. If you're having problems with Spotlight searching, try re-indexing your drive.
Spotlight: How to re-index folders or volumes
That's because, in most cases, app removal software such as AppZapper doesn't do a thorough job of finding and removing files/folders related to deleted apps. For more information, read
this. If you just want to delete the app, drag the .app file to the trash. No other software needed. If you want to completely remove all associated files/folders, no removal apps will do the job.
The most effective method for complete app removal is manual deletion:
As for your formatting issues:
Format A Hard Drive Using Disk Utility (which is in your /Applications/Utilities folder)
Choose the appropriate format:
FAT32 (File Allocation Table)
- Read/Write FAT32 from both native Windows and native Mac OS X.
[*]Maximum file size: 4GB.
- Maximum volume size: 2TB
- You can use this format if you share the drive between Mac OS X and Windows computers and have no files larger than 4GB.
NTFS (Windows NT File System)
- Read/Write NTFS from native Windows.
- Read only NTFS from native Mac OS X
[*]To Read/Write/Format NTFS from Mac OS X, here are some alternatives:
- For Mac OS X 10.4 or later (32 or 64-bit), install Paragon (approx $20) (Best Choice for Lion)
- For 32-bit Mac OS X, install NTFS-3G for Mac OS X (free) (does not work in 64-bit mode)
- For 64-bit Snow Leopard, read this: MacFUSE for 64-bit Snow Leopard
- Some have reported problems using Tuxera (approx $36).
- Native NTFS support can be enabled in Snow Leopard and Lion, but is not advisable, due to instability.
- AirPort Extreme (802.11n) and Time Capsule do not support NTFS
- Maximum file size: 16 TB
- Maximum volume size: 256TB
- You can use this format if you routinely share a drive with multiple Windows systems.
HFS+ (Hierarchical File System, a.k.a. Mac OS Extended (Journaled) Don't use case-sensitive)
exFAT (FAT64)
- Supported in Mac OS X only in 10.6.5 or later.
- Not all Windows versions support exFAT. See disadvantages.
- exFAT (Extended File Allocation Table)
- AirPort Extreme (802.11n) and Time Capsule do not support exFAT
- Maximum file size: 16 EiB
- Maximum volume size: 64 ZiB
- You can use this format if it is supported by all computers with which you intend to share the drive. See "disadvantages" for details.
