Bcrypt Blowfish Unix Hash

[Gumshoe]

Thanks royce, I think everything working good but wondering why its impossible to crack a 6-digit numerical code? Here what I get:
I used this command:
./hashcat -m 3200 -a 3 -1 ?d /Users/gumshoe/Documents/Hash.lst ?1?1?1?1?1?1

I got this:

OpenCL Platform #1: Apple
=========================
* Device #1: Intel(R) Core(TM) i5-5350U CPU @ 1.80GHz, skipped.
* Device #2: Intel(R) Iris(TM) Graphics 6100, 384/1536 MB allocatable, 48MCU

Hashes: 1 digests; 1 unique digests, 1 unique salts
Bitmaps: 16 bits, 65536 entries, 0x0000ffff mask, 262144 bytes, 5/13 rotates

Applicable optimizers:
* Zero-Byte
* Single-Hash
* Single-Salt
* Brute-Force

Minimum password length supported by kernel: 0
Maximum password length supported by kernel: 72

Watchdog: Temperature abort trigger disabled.

* Device #2: Skipping unstable hash-mode 3200 for this device.
You can use --force to override, but do not report related errors.

Then I used --force command for device 2

./hashcat -m 3200 --force -a 3 -1 ?d /Users/gumshoe/Documents/Hash.lst ?1?1?1?1?1?1

It worked and got this:

Finally it completed the attack in 10 minutes but nothing recovered. How strange?
